FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with acetylene is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about acetylene, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to acetylene, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on acetylene. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to acetylene, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on acetylene. The Editors

CHAPTER 1. STUDIES ON ACETYLENE Overview In this chapter, we will show you how to locate peer-reviewed references and studies on acetylene.
Federally Funded Research on Acetylene The U.S. Government supports a variety of research studies relating to acetylene. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to acetylene. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore acetylene. The following is typical of the type of information found when searching the CRISP database for acetylene: •
Project Title: BIOINORGANIC COPPER COORDINATION CHEMISTRY Principal Investigator & Institution: Karlin, Kenneth D.; Professor; Chemistry; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 01-APR-1990; Project End 31-MAR-2003 Summary: The long term objective of the proposed research is the development of the fundamental coordination chemistry of copper ion as it pertains to the active site

chemistry of proteins involved in O2-transport, O2- activation (e.g., monooxygenation, N-dealkylation) and O2-reduction. Through detailed studies of chemical model systems, a reasonable basis for hypothesis of biological structure and competency of intermediates can be made. There exists a paucity of information about Cu(I) coordination chemistry, and its reactions with O2/substrate. Our interests are in functional modeling, i.e., reactions of CuI/O2 and CuI/O2/substrate. The structures, spectroscopy and reactivity of possible intermediates such as Cu-O2-Cu, Cu-OOH, CuO-Cu and Cu-O are poorly understood. Systematic investigations using model compounds with varied, but known structure, ligation and associated CuII/CuI redox potential can lead to a better understanding of the biological transformations. The proposed research is divided into sub-projects, directed along various themes, questions, or chemical systems. We plan to study: (1) Cu-pterin interactions, to help elucidate the active site chemistry of Cu-phenylalanine hydroxylase. Chelating pterins will be used to study Cu/O2 reactions with reduced pterins and substrates. (2) Chemistry with tripodal tetradentate ligands, including dinucleating versions. Both Cu/O2 1:1 and 2:1 adducts should form and comparisons of structure, kinetics/thermodynamics and reactivity will provide fundamental information. (3) L2CuI/O2 + L' and LnCuI-X (X = CO, CN-, RNC, acetylene) chemistry with L as a biologically 'relevant' unidentate imidazole ligand. The latter compounds will help in developing spectroscopic probes for protein reduced Cu(I) ion. (4) The chemistry of side-on bound peroxo dinuclear complexes. Modified ligands will help probe structure and reactivity of these species, which are capable of effecting arene hydroxylation reactions. In addition to studies with 'endogenous' substrates, we will develop CuI/O2 chemistry using organic receptors for 'exogenous' substrates, such as cyclodextrins and those based on a diphenylglycoluril building block. (5) The chemistry of unsymmetrical dinuclear complexes will be developed. This is relevant to a number of Cu proteins, where one Cu ion (or cofactor) passes electrons to another which effects O2/substrate reactions. (6) Hydroperoxide-Cu interactions, which are involved in proteins such as dopamine b-hydroxylase and others. We will also investigate and compare structure, spectroscopy and reactivity of systems which are 'reductively activated', i.e., with Cu(I) complex reactions with ROOH. (7) Oxidative N-dealkylation chemistry using Cu-ligand systems observed to undergo such reactions; structures of intermediates and mechanism will be determined. (8) The chemistry of tri- and tetranuclear Cu complexes and their O2 reactions; Cu clusters occur in laccase & ascorbate oxidase and possibly in Cu methane monooxygenase. (9) O2-binding and reduction chemistry at porphyrin-Fe/Cu complexes, as structural/functional models for reactions occurring in cytochrome c oxidase.

Project Title: CHEMOTHERAPY DRUG ANALYZER Principal Investigator & Institution: Farquharson, Stuart; Real-Time Analyzers 87 Church St East Hartford, Ct 06108 Timing: Fiscal Year 2002; Project Start 27-SEP-2002; Project End 26-SEP-2003 Summary: (provided by applicant): The overall objective of the proposed program is to develop a bed-side analyzer capable of providing rapid identification and quantification of chemotherapy drugs and metabolites in serum and urine. The analyzer would allow optimizing effectiveness and minimizing adverse side-effects associated with chemotherapy drugs administered during cancer treatment. The analyzer will use capillary electrophoresis to separate drugs from body fluids with minimal sample preparation, Raman spectroscopy to identify the drugs, and surface-enhanced Raman

spectroscopy (SERS) to increase sensitivity and allow quantification at physiologic concentrations. The Phase I program will demonstrate feasibility through three tasks with the following objectives: 1) develop the SER active sol-gel chemistry for selective adsorption of polar or nonpolar and positive or negative chemical groups; 2) test and refine chemical selectivity and SER activity of the sol-gels using p-aminobenzoic acid, phenyl acetylene, benzoic acid, aniline, camptothecin, carboplatin, cyclophosphamide, 5-fluorouracil, and 8-oxyguanine; and 3) test ability to selectively measure these chemicals and drugs with detection limits of <50 ng/ml and 5 ng/ml in simulated serum and urine samples, respectively. In Phase II a prototype bed-side analyzer will be engineered and head-to-head comparisons to existing technology will be performed.

Project Title: INACTIVATION OF CYTOCHROMES P450 2E1 T303A Principal Investigator & Institution: Blobaum, Anna L.; Pharmacology; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-AUG-2005 Summary: (provided by applicant): The ethanol-inducible cytochrome P450 2E1 catalyzes the oxidation of a large number of drugs, hepatotoxic xenobiotics, and carcinogens. The primary goals of the proposed research are to gain a better understanding of the active site structure of P450 2E1 and to identify the critical amino acid residues in the active site of 2E1 that are involved in catalysis and substrate binding. High performance liquid chromatography (HPLC) and electrospray ionization liquid chromatography-mass spectrometry (ESI-LC-MS) will be used to determine the identities of the metabolites produced during the mechanism-based inactivation of cytochromes P450 2E1 and 2E1 T303A by tert-butyl acetylene (tBA) and tert-butyl 1methyl-2-propynyl ether (tBMP). LC-MS/MS (liquid chromatography-mass spectrometry/mass spectrometry) will be used to identify the tBA-modified polypeptide(s) and amino acid residue(s) in the P450 2E1 active site. NMR methodology and site-specific 2E1 mutants will be used to explore the novel mechanism for the inactivation of P450 2E1 T303A by tBA. Finally, ESI-LC-MS will be used to determine what effect alternate oxidants may have on the mechanism of inactivation of P450s 2E1 and 2E1 T303A by tert-butyl acetylenes. Understanding the active site structure of P450s and identifying the critical amino acid residues involved in catalysis and substrate binding will prove to be extremely valuable for developing techniques that can be used to selectively modulate the catalytic activity of these enzymes.

Project Title: REGULATION OF MUSCLE BLOOD FLOW IN OLD AGE Principal Investigator & Institution: Proctor, David N.; Assistant Professor; Noll Physiological Res Ctr; Pennsylvania State University-Univ Park 110 Technology Center University Park, Pa 16802 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 30-JUN-2004 Summary: The goal of this application is to test the hypothesis that human aging alters the regulation of blood flow to active skeletal Skeletal muscles during whole body exercise. Compelling evidence supporting this hypothesis comes from our recent finding that leg blood flow during submaximal cycle ergometry is reduced in older versus younger aerobically-trained men, despite similar cardiac output and leg muscle mass. To determine if reduced skeletal muscle perfusion duration exertion is an inevitable consequence of aging, and to clarify the mechanisms involved, we will

address the following specific aims: 1) Is active muscle blood flow during exercise influenced by age, gender, or chronic physical activity? 2) Does an acute reduction in the work of breathing (inspired HeO2) during submaximal exercise augment active muscle blood flow to a greater extent in older compared to younger subjects and if so, how? 3) Is there evidence for an age-associated increase in sympathetic vasoconstriction in active skeletal muscle during exercise and if so, is this related to differences in muscle fiber type (needle biopsy)? 4) Does an aerobic exercise training program modify the effects of age on exercise hyperemia and vasodilator responsiveness in the leg? These questions will be investigated by measuring leg blood flow (femoral vein thermodilution), leg norepinephrine spillover, arterial pressure, and cardiac output (acetylene uptake) during graded leg cycle ergometry in healthy younger z920-30 years) and older (60-75 years) men and women. Leg muscle mass (DEXA) and leg vasodilator responses to local administration of prazosin (Aim 3) and endothelial-dependent and independent agonists (ACh, NTP, papavarine, Aim 4) will also be assessed as a function of age. We hypothesize that normal aging is associated with reduced active muscle vasodilation during dynamic exercise and that this is due to increased respiratory muscle blood flow demands, augmented sympathetic vasoconstriction in the legs, and impaired respiratory muscle blood flow demands, augmented sympathetic vasoconstriction in the legs, and impaired endothelium-dependent vasodilation. These investigations should contribute significantly to our understanding of the decline in physical functional capacity and increased incidence of chronic disease in older humans.

Project Title: SYNTHESIS OF MDR REVERSING POLYENES Principal Investigator & Institution: Andrus, Merritt B.; Professor; Chemistry and Biochemistry; Brigham Young University A-261 Asb Provo, Ut 846021231 Timing: Fiscal Year 2002; Project Start 01-APR-1999; Project End 31-MAR-2004 Summary: Multi-drug resistance (MDR) is due to the expression of Pgp (Pglycoprotein), by the MDRl gene, an ATP-driven membrane-bound multi-drug transporter. Recently we have developed synthetic routes to new MDR reversal agents, stipiamide, and a more potent, non-toxic compound 6,7- dehydrostipiamide (DHS, fig.1) that restores the cytotoxicity of adriamycin to resistant human breast cancer cells (MCF7adrR) at very low concentrations (4 nM). We will now investigate new compounds possessing non-natural spacers, in combinatorial libraries, and benzophenone photolabels. Non-natural polyenes will be produced to identify the optimal structural requirements for MDR reversal using assays with resistant cancer cell lines and purified Pgp. The polyene region of stipiamide will be changed to minimize toxicity and increase MDR reversal. Bi-directional cross coupling reactions with para- disubstituted benzenes will be investigated to selectively attach the two ends. Competition studies with known radiolabeles will be used to verify the direct Pgp binding. The toxicity of each compound will be determined using normal cancer cells and resistant cell lines with added cancer drug. Alternative routes to the anti-1,2-hydroxy methyl will be investigated with chiral auxiliaries and catalytic aldol approaches. The functionality at the two ends and the stereochemistry will be probed using combinatorial libraries. The conditions of the coupling will be optimized at 1:1 iodide:acetylene stoichiometry and applied to the combinatorial libraries. The compounds will be assayed as mixed pools using the MCF-7adrR MDR assay. Specific residues on Pgp will be identified, for the first time, using high-efficiency benzophenone- stipiamide photoaffinity labeler. Microsequencing will be used to identify specific residues found in the binding site. Bifunctional dual-domain compounds will also be made by linking two MDR reversal

compounds through the terminal amide. Reversal assays with these compounds will be used to establish the distance constraints between Pgp transmembrane helices TM6 and TM12 that have been implicated to contain the drug and reversal agent binding sites. Results from the libraries, the bi-functional compounds, and the photolabels will establish, for the first time, the location, the binding characteristics, and the distances between the binding bites on Pgp. Data obtained from these experiments will have direct bearing on the 3D-structure of Pgp. This is an important first step toward a molecular understanding of the unique recognition properties, transport mechanism of Pgp, and will further facilitate the design of new, more potent reversal agents.

Project Title: TECHNIQUE FOR DETERMINATION OF CARDIAC OUTPUT DURING HEAVY EXERCISE Principal Investigator & Institution: Johnson, Bruce E.; Mayo Clinic Coll of Medicine, Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2002 Summary: The following protocol seeks to validate a non-invasive open circuit method for determination of cardiac output (pulmonary blood flow) at rest and during heavy exercise using simple gas exchange based measures. There are relatively few noninvasive techniques that give valid estimates of cardiac output at rest and during heavy whole body exercise. The acetylene rebreathing technique has been used extensively over the last 10-15 years and has been validated with thermodilution and Fick estimates of cardiac output in exercising humans and dogs. In this technique, the highly soluble gas, acetylene, is taken up in the lungs in direct proportion to the blood passing through the pulmonary circulation. A drawback to the rebreathing technique is the fact carbon dioxide builds up and oxygen decreases in both the rebreathing bag and lungs. The build up of CO2 causes increased dyspnea, particularly in patients with poor lung function and limited exercise tolerance. The transient changes in the VC02/V02 relationship make it difficult to control for changes in the lung-rebreathing bag volume which can lead to errors in the estimate of cardiac output. In addition, rebreathing may lead to alterations in breathing pattern, which also may cause changes in the cardiac output. Recently, an open circuit acetylene technique that offers several advantages over the rebreathing technique has been developed but not validated in humans. The present study proposes to validate the open circuit technique more fully in exercising humans against the already established technique, and the standard techniques to measure cardiac output using thermodilution and Fick. The specific aims of this study are to compare an open circuit acetylene uptake technique for determination of cardiac output with the traditional acetylene rebreathing technique; and to compare an open circuit acetylene technique for determination of cardiac output at rest and during exercise to the standard thermodilution and Fick measurements of cardiac output.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with acetylene, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “acetylene” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for acetylene (hyperlinks lead to article summaries): •

PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND ACETYLENE Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and acetylene.
Finding Nutrition Studies on Acetylene The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “acetylene” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 5. PATENTS ON ACETYLENE Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.8 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “acetylene” (or a synonym) in their titles.

Aqueous coating composition Inventor(s): Fritcher; Jesse (Lansing, IL), Kim; Juhan (Annarbor, MI), Makarewicz; Jeffrey (Annarbor, MI) Assignee(s): Nippon Bee Research America, Inc. (Lansing, IL), Toyota Technical Center, U.S.A., Inc. (Annarbor, MI) Patent Number: 6,613,826 Date filed: September 1, 2001 Abstract: The present invention provides: a high viscosity aqueous coating composition, which can be coated onto plastic materials such as polyolefin materials by a HVLP gun, and which has excellent sagging performance and can obtain a coating film with good appearance. The aqueous coating composition comprises an acetylene diol defoamer and a silicone wetting agent in addition to a film-formable component, wherein the nonvolatile solid content of the acetylene diol defoamer is in the range of 0.25 to 1.0 weight % of the entirety of the aqueous coating composition, and the nonvolatile solid content of the silicone wetting agent is in the range of 0.75 to 2.0 weight % of the entirety of the aqueous coating composition. Excerpt(s): The present invention relates to an aqueous coating composition which can improve poor appearance caused when plastic materials are directly coated with the composition by a high-volume-low-pressure (HVLP) gun, namely, which gives good sprayability. Plastic materials utilized for automotive interior parts include polypropylene (PP), acrylonitrile-butadiene-styrene (ABS), poly(phenylene oxide) (PPO) and polycarbonate (PC). In recent years, polyolefin materials are getting often used in view of cost and recyclability. Until now, these plastic materials were coated with organic solvent type paints or aqueous paints by spray guns, such as a HVLP gun and a conventional air-spray gun.

Excerpt(s): This invention deals generally with wear and corrosion resistant coatings on metal and more specifically with a coating for plastic injection molds. Over the last decade, diamond-like carbon coatings deposited on various tools and parts have gained wide acceptance for wear and corrosion protection. The diamond-like carbon coatings demonstrate a unique combination of properties that include high hardness in excess of 2,000 GPa and extremely low coefficients of friction and surface tension. Furthermore, they are chemically inert when in a variety of aggressive environments and have an aesthetically attractive appearance. Such diamond-like carbon coatings are amorphous, which means that they do not have long range repeatability of atomic positions in their crystalline structure. In recent years diamond-like carbon films have been introduced for coating molds that are used for plastic injection molding where the anti-sticking properties of the diamond-like carbon coatings allow for reduced downtime, longer mold life, and improved product quality. Diamond-like carbon films have been particularly beneficial when used for the protection of the working surfaces of the molds and the mold parts used for manufacturing optical media discs such as CDs, DVDs, and the like. Although discs manufactured with diamond-like carbon film coated molds generally outperform those from uncoated or titanium nitride coated molds, the field performance of diamond-like carbon coated molds varies for different methods of depositing the diamond-like carbon.

Chemical sensors and method of use Inventor(s): Glass; Timothy E. (State College, PA), Moran; Ricardo (Washington, DC), Raker; Joseph (State College, PA) Assignee(s): The Penn State Research Foundation () Patent Number: 6,586,256 Date filed: May 2, 2000 Abstract: Chemical sensor compositions and methods for quantifying analytes are described. The chemical sensors include analyte-binding moieties and reporter moieties covalently attached to a framework including two trityl groups connected by a linear spacer such as ethyne or butadiyne. The sensors chelate an analyte across the acetylene axis of the molecule to stabilize the molecule in an eclipsed rotamer conformation. This conformation causes the sensors to emit a measurable signal. Also disclosed are methods of making the chemical sensors, methods of using the chemical sensors, and kits for quantifying analytes using the chemical Excerpt(s): The present invention relates to compounds for quantifying analytes. In particular, the present invention relates to small molecule compounds that have analytebinding moieties functionally linked to reporter moieties. The reporter moieties of these molecules emit a measurable signal when the analyte-binding moieties interact with the analyte. Chemical sensors or chemosensors are small synthetic molecules that produce a measurable signal upon interaction with a specific analyte. They are used to determine the concentration of an analyte without involving complicated analytical techniques or having to "disturb" the system being analyzed. Numerous uses for chemosensors exist. For example, in the biochemical community, they have been used as sensitive, nondestructive probes for quantifying the amount of a particular analyte in living cells. In the medical industry, chemosensors are used for quickly quantifying the amount of certain analytes in bodily fluids such as blood or urine. Myriad other applications for chemosensors exist, including, for example, monitoring pollutants in waste water and

quantifying contaminants in chemical compositions. See, Chemosensors of Ion and Molecule Recognition, Desvergne, J- P.; Czarnik, A. W., Eds.; NATO ASI Series C: 492; Kluwer: New York, 1997; "Signaling Recognition Events with Fluorescent Sensors and Switches" de Silva, A. P.; Gunaratne, H. Q. N.; Gunnlaugsson T.; Huxley, A. J. M.; McCoy, C. P.; Radermacher, J. T.; Rice, T. E. Chem. Rev. 1997, 97, 1515; "Desperately Seeking Sensors" Czamik, A. W., Chem. and Bio. 1995, 2, 423; Fluorescent Chemosensors for Ion and Molecule Recognition, Czarnik, A. W. (Ed.), ACS Symp. Set. 538; ACS: Washington D.C., 1993. Several molecules that can serve as chemosensors have previously been developed (see, e.g., http://www.molecularprobes.com). These compounds are typically designed to have an analyte-binding moiety functionally connected to a fluorescent reporter moiety. Binding of the analyte of interest by the analyte-binding moiety causes a conformational change in the chemosensor molecule that results in the modulation of the fluorescence of the reporter moiety. For example, fluorescence resonance energy transfer (FRET) may result when two fluorescent moieties are brought into close proximity by the steric change of a chemosensor molecule caused by analyte-binding. FRET alters the fluorescence emission of the reporter moiety, resulting in a measurable signal from which the analyte concentration can be extrapolated. Other chemosensor molecules produce a visible color change upon binding an analyte. Analyte-binding by these molecules alters their conformation so that in solution they absorb visible light differently and thereby cause a color change.

Coating liquid, and image recording method and recording using same Inventor(s): Hara; Kazuhiko (Nagano, JP), Ito; Fumitsugu (Nagano, JP), Komatsu; Hidehiko (Nagano, JP), Ota; Hitoshi (Nagano, JP), Yatake; Masahiro (Nagano, JP) Assignee(s): Seiko Epson Corporation (Tokyo, JP) Patent Number: 6,723,784 Date filed: April 10, 2001 Abstract: A coating liquid for forming a transparent topcoat, without requiring a hardening or fixing process that uses heating or UV radiation. The coating liquid imparts light resistance, water resistance, fixation, and glossiness to recordings. Also, a recording method using the coating liquid, and recordings produced thereby. The liquid, which is applied to recorded images, contains at least water, fine polymer particles, and a penetrating agent, preferably a penetrating agent selected acetylene glycol surfactants, acetylene alcohol surfactants, glycol ethers, and 1,2-alkylene glycols. Also, an image recording method for forming an even, transparent coating layer by spraying the coating liquid during an ink jet recording process, as well as recordings produced thereby. Excerpt(s): This invention relates to a coating liquid used in methods for coating recorded images, to an image recording method using that coating liquid, and to a recordings recorded therewith. Conventionally, the method of coating a recorded image with a laminate film is practiced as a method for protecting the recorded image and enhancing the bond between the recorded image and the base material. With this method, however, because separate process steps are required for supplying the laminate film, coating, and pressure application and the like, the apparatus itself becomes complex. With further innovations needed to effect suitable coatings, in Japanese Patent Application Laid-Open No. S59-104974/1984 (published), an apparatus is proposed for effecting good and suitable laminate coatings by the new addition, to the
Patents 37
process, of an apparatus for detecting laminate film layer displacement. With this, however, the apparatus becomes even larger and more complex. Ink jet recording, on the other hand, is a method wherewith text or graphics are recorded on the surface of a recording medium by ejecting small droplets of ink from very small nozzles. The ink jet recording procedures being implemented in practice include a method wherewith electrical signals are converted to mechanical signals using an electrostriction transducer, and ink stored in a nozzle head portion is discharged intermittently and text or symbols are recorded on the surface of a recording medium, and a method wherewith a part extremely close to the portion ejecting the ink stored in the nozzle head portion is rapidly heated to generate bubbles, intermittent ejection is effected by the cubical expansion of those bubbles, and text or symbols are recorded on the surface of a recording medium.

Conductive melt-processible fluoropolymer Inventor(s): Ishii; Kasuke (Shimizu, JP), Kondo; Shosaku (Shimizu, JP), Lee; Jeong Chang (Shimizu, JP), Sato; Hajime (Shimizu, JP), Suzuki; Noriyuki (Shimizu, JP) Assignee(s): DuPont Mitsui Fluorochemicals (Tokyo, JP) Patent Number: 6,582,628 Date filed: May 21, 2002 Abstract: A method for producing an electrically conducting melt-processible fluoropolymer comprising pulverizing a composition of (a) carbon aggregate and (b) coagulum particles of aqueous dispersion polymerized melt-processible fluoropolymer, coating the coagulum particle with the disintegrated particles of carbon black. The preferred composition comprises a structured carbon black such as acetylene black and a melt processible fluoropolymer wherein said melt processible fluoropolymer has two crystallization peaks in a DSC cooling curve when allowed to crystallize from a temperature of not less than its melting point at a cooling rate of 12.degree. C./min; and the ratio of the crystallization peak heights (high temperature side peak/low temperature side peak) is 0.65 or greater; and/or the ratio of the high temperature side crystallization peak area to the total area of the crystallization peaks [high temperature side peak area/(high temperature side peak area+low temperature side peak area)] is 0.18 or greater. Excerpt(s): This invention relates to melt-processible fluoropolymer rendered conductive by the incorporation of carbon black. Fluoropolymers are used in containers and hoses for flammable fluids because they are little affected by such fluids and also are highly impermeable to them. Because the containers and hoses should have some electrical conductivity to prevent the accumulation of static charge, which can cause safety problems, fillers are added to the fluoropolymers to confer electrical conductivity. To obtain articles having uniform electrical conductivity, it is desirable that fillers that impart conductivity be uniformly distributed. Japanese Kokai Patent Hei 11 (1999)-35694 discloses a method for granulation of melt-processible fluoropolymer by the addition of polyfluoroalkyl alkyl ether to aqueous fluorocarbon dispersion. The resultant fluoropolymer powder granules have a large average particle size (1.0 to 1.5 mm according to the Examples). Addition of conductive filler to these granules leads to uneven distribution of the filler and this adversely affects conductivity of articles meltfabricated from the granule/filler mixture.

Conjugated copolymers of dithienothiophene with vinylene or acetylene Inventor(s): Farrand; Louise Diane (Blandford Forum, GB), Giles; Mark (Southampton, GB), Heeney; Martin (Southampton, GB), McCulloch; Iain (Kings Somborne, GB), Shkunov; Maxim (Southampton, GB), Sparrowe; David (Bournemouth, GB), Thompson; Marcus (Fordingbridge, GB), Tierney; Steven (Southampton, GB) Assignee(s): Merck Patent GmbH (Darmstadt, DE) Patent Number: 6,645,401 Date filed: August 19, 2002 Abstract: Conjugated copolymers of dithienothiophene with vinylene or acetylene are suitable for use as semiconductors or charge transport materials in optical, electrooptical or electronic devices including field effect transistors, electroluminescent, photovoltaic and sensor devices. Excerpt(s): The invention relates to new conjugated copolymers of dithienothiophene with vinylene or acetylene (ethinylene). The invention further relates to methods of their preparation, to their use as semiconductors or charge transport materials in optical, electrooptical or electronic devices including field effect transistors, electroluminescent, photovoltaic and sensor devices. The invention further relates to field effect transistors and semiconducting components comprising the new polymers. Organic materials have recently shown promise as the active layer in organic based thin film transistors and organic field effect transistors [see reference 1]. Such devices have potential applications in smart cards, security tags and the switching element in flat panel displays. Organic materials are envisaged to have substantial cost advantages over their silicon analogues if they can be deposited from solution, as this enables a fast, large-area fabrication route. The performance of the device is principally based upon the charge carrier mobility of the semiconducting material and the current on/off ratio, so the ideal semiconductor should have a low conductivity in the off state, combined with a high charge carrier mobility (>1.times.10.sup.-3 cm.sup.2 V.sup.-1 s.sup.-1). In addition, it is important that the semiconducting material is relatively stable to oxidation, i.e., it has a high ionisation potential, as oxidation leads to reduced device performance.

comprised of a central polybenzoxazole, polybenzothiazole, polyamic acid or polyamic acid ester segment end-capped at each terminus with an aryl-substituted acetylene moiety such as an ortho-bis(arylethynyl)aryl group, e.g., 3,4-bis(phenylethynyl)phenyl. Integrated circuit devices, integrated circuit packaging devices, and methods of synthesis and manufacture are provided as well. Excerpt(s): This invention relates generally to dielectric materials and their use in integrated circuits. More particularly, the invention pertains to novel dielectric polymer compositions, oligomeric precursors and methods for preparing the compositions, and integrated circuit devices fabricated therewith. Polyimides are known in the art for use in the manufacture of integrated circuits including chips (e.g., chip back end of line, or "BEOL"), thin film packages, and printed circuit boards. Polyimides are useful in forming dielectric interlayers, passivation layers, alpha particle barriers, and stress buffers. Polyimides are particularly useful as an interlayer dielectric material to insulate the conductor wiring interconnecting the chips on a multichip module. This is known as "thin film" wiring. Multichip modules represent an intermediate level of packaging between the chips and the circuit board, and are generally known in the art. Multichip modules are made up of multiple layers of power, signal, and ground planes which deliver power to the chips and distribute the input/output signals between chips on the module or to and from the circuit board. There is a continuing desire in the microelectronics industry to increase the circuit density in multilevel integrated circuit devices, e.g., memory and logic chips, thereby increasing performance and reducing cost. In order to accomplish these goals, those in the field are striving to reduce the minimum feature sizes, e.g., metal lines and vias, and to decrease the dielectric constant of the interposed dielectric material to enable closer spacing of circuit lines without a concomitant increase in crosstalk and capacitive coupling. Polyimides usually have dielectric constants of about 3.0-3.8 and mechanical and thermal properties sufficient to withstand present processing operations including the thermal cycling associated with semiconductor manufacturing. However, there is a need in the art for a dielectric material that would be suitable for use in integrated circuit devices, wherein the material exhibits a lower dielectric constant (e.g., <3.0) than typically exhibited by polyimides and has improved mechanical and thermal properties.

Excerpt(s): This invention relates to electric heating fabrics, and more particularly to an electric heated cloth and method for the generation and maintenance of a required temperature in a certain local zone. The invention also relates to a conducting resistive thread used in the heated cloth. Present-day demands to control temperatures generate a high interest in flexible electric heating devices that may be used to ensure environment adaptation to a temperature parameter. Cloth heaters are a type of flexible electric heater representing a flexible means of heating various surfaces and media that are easily adapted to the application site. Among the devices that require use of cloth electric heaters are automotive heated seats, heated steering wheels, automotive engine oil crankcases, cement hardening heaters, clothes with heating elements, thermal blankets, etc. In some applications, such as automotive seat heaters, it is desirable that permanent operating heater temperature of approximately 37.degree. C. be maintained, with provisions to raise it to about 150.degree. C. within a short period of time during fabrication of seats in order to ensure melting of an adhesive material that ensures gluing of the car seat material to a foam.

Properties required of inks used in the ink jet recording includes a good drying property of the print, no feathering created, homogeneous printing performed on the surface of various recording medium, and, in the case of multi-color printing, no color-to-color intermixing occurred. Feathering on paper occurs attributable to the presence of fibers different from each other in ink penetration, a black ink and a color ink are intermixed at the boundary therebetween to deteriorate the image quality.

Internal combustion system adapted for use of a dual fuel composition including acetylene Inventor(s): Hulett; Maynard (Columbia, MO), Lee; Sunggyu (Columbia, MO), Wulff; Joseph W. (Hallsville, MO) Assignee(s): Go-Tec (Columbia, MO) Patent Number: 6,575,147 Date filed: March 21, 2000 Abstract: An internal combustion engine adapted to use an environmentally clean multifuel composition, comprising acetylene as a primary fuel and a combustible fuel, such as one or more fluids selected from an alcohol such as ethanol, methanol or any other alcohol or alcohols from the group comprising C.sub.1 -C.sub.12 carbon chains, ethers such as from the group comprising dimethyl ether, diethyl ether, methyl t-butyl ether, ethyl t-butyl ether, t-amyl methyl ether, di-isopropyl ether and the like, low-molecularweight esters such as from the group comprising methyl formate, methyl acetate, ethyl acetate, methyl propionate, ethyl propionate, ethyl malate, butyl malate, and the like, or other suitable combustible fluid such as mineral spirits and the like, as a secondary fuel for operatively preventing early ignition and knock arising from the primary fuel. Excerpt(s): The present invention relates to a system using fuel comprising at least two combustible ingredients and more particularly, without limitation, to an internal combustion engine using fuel comprising acetylene and another combustible fuel. Acetylene is conventionally produced by reacting calcium carbide with water. The reaction is spontaneously occurring and can be conducted without any sophisticated equipment or apparatus. Such produced acetylene has been utilized for lighting in mine areas, by street vendors, etc. People often call such lighting sources "carbide lights" or "carbide lamps". Industrial uses of acetylene as a fuel for motors or lighting sources, however, has been nearly nonexistent. In modern times, the use of acetylene as a fuel has been largely limited to acetylene torches for welding or welding-related applications. In most such applications, acetylene is generally handled in solution form, such as acetylene dissolved in acetone for example. The reaction proceeds spontaneously at any temperature and pressure conditions and easily goes to completion without leaving any residues other than the desired combustion products,
42
Acetylene
namely carbon dioxide and water. Further, the reaction ideally takes place in a gaseous phase without any need for catalytic assistance. The gas-phase reaction has several advantages over heterogeneous reactions such as gas-liquid, gas-solid, and solid-liquid reactions. For example, the gas-phase reaction does not require much effort for mixing necessary ingredients, assuring proper ratios, or handling by-products of combustion. Such advantages become very significant in fuel applications for combustion engines where liquid fuels such as gasoline have been conventionally used, and gasoline (liquidphase) and air (gas-phase) interact contact in an engine for combustion reaction purposes.

Liquid crystal composition, color filter and optical film Inventor(s): Ichihashi; Mitsuyoshi (Shizuoka-ken, JP) Assignee(s): Fuji Photo Film Co., Ltd. (Kanagawa, JP) Patent Number: 6,645,397 Date filed: June 6, 2001 Abstract: An objective of the present invention is to provide a liquid crystal composition whose orientation undergoes a large change upon irradiation with light, and which also has a large birefringence.DELTA.n. The liquid crystal composition contains an aromatic acetylene compound and a chiral compound that undergoes a structural change upon photoreaction, and has such properties that, upon irradiation with light, its helical pitch undergoes a large change in accordance with the level of the light intensity, and that has a large birefringence.DELTA.n. Therefore, the present invention makes it possible to provide a reflection type color filter which utilizes the liquid crystal composition, and which provides a lighter display with high reflectance. Moreover, the present invention also provides an optical film that can be formed as a thinner film using the liquid crystal composition. Excerpt(s): The present invention relates to a liquid crystal composition, a color filter and an optical film using such a liquid crystal composition. In general, a color filter used for a color liquid crystal display, etc., is composed of, red (R), green (G) and blue (B) pixels respectively, and black matrixes that are formed between the pixels so as to improve display contrast. Conventionally, the color filter of this type has been mainly formed by dispersing a pigment into a resin or dyeing a resin with a dye. In the manufacturing method also, such a colored resin liquid is coated onto a glass substrate by spin coating, etc., to form a colored resist layer. This is patterned by photolithography to form a color filter pixel, or a colored pixel is printed directly on a substrate; thus, a color filter is manufactured. However, in the manufacturing method of a color filter using a printing method, there is a drawback in that the pixel resolution is low and it is difficult to produce a high-resolution image pattern. In the manufacturing method using the spin coat method, there is also a drawback in that there is a large amount of material loss. Further, it is generally necessary to carry out mask exposure three times in order to form R, G & B pixels respectively, and as a result the manufacturing process is complex and manufacturing cost is high. The color filter is required to have properties of high transmittance and high color purity. In a method in which a dye is used, transmittance and purity may be improved by optimizing the type of dye and the color resin. Also, in a method using a pigment, transmittance and purity may be improved by using a fine pigment which is more thoroughly dispersed. However, since all of the conventional color filters are color filters of the light-absorbing
Patents 43
type, there is a limit to how much the color purity can be improved by improving the transmittance. In recent years, there have been high demands for transmittance and color purity of color filters used, in liquid crystal display (LCD) panels. In particular, in reflection-type LCD color filters, it is very difficult to simultaneously achieve a degree of whiteness like white paper, contrast and color reproducibility, but there have been particularly high demands for color filters having these properties.

Lithium secondary battery Inventor(s): Kitoh; Kenshin (Nagoya, JP), Kurokawa; Teruhisa (Aichi-prefecture, JP) Assignee(s): NGK Insulators, Ltd. (Nagoya, JP) Patent Number: 6,569,557 Date filed: September 9, 1999 Abstract: A lithium secondary battery includes: an internal electrode body including a positive electrode, a negative electrode, and a separator, the positive electrode and the negative electrode being wound or laminated via the separator, and an organic electrolyte. The active material used in the positive electrode satisfies the following relation between the average particle diameter R (.mu.m) and the specific surface area S (m.sup.2 /g):6.ltoreq.R.times.S.ltoreq.50The amount of the acetylene black added to the positive electrode active material satisfies the following relation with the specific surface area of the positive electrode active material:S.ltoreq.W.ltoreq.S+5 (W.ltoreq.10)(W is the amount of the acetylene black added to the positive electrode active material, expressed in % by weight based on the amount of the active material, and S is expressed in m.sup.2 /g.) In this battery, the electron conductivity is improved, and the internal resistance is reduced. Excerpt(s): The present invention relates to a lithium secondary battery wherein the electron conductivity of the positive electrode active material layer is improved, the internal resistance is reduced, and discharging in large output and in large current is possible and which can be suitably used particularly as an electric source for driving of the motor of an electric vehicle or the like. In recent years, as the movement for environmental protection has become active, it has become a serious issue to control the exhaust gas (e.g. carbon dioxide and other harmful materials) emitted from internal combustion engines or to save energy. In this connection, it has become common, in the automobile industry, to investigate the market introduction, as early as possible, of electric vehicles (EVs) or hybrid electric vehicles (HEVs) in place of conventional automobiles using fossil fuels (e.g. gasoline). As the battery used for driving of the motor of EV or HEV, a lithium secondary battery is promising for its high energy density. In order for an EV or HEV to exhibit sufficient performance in acceleration, slope-climbing property, continuous running property, etc., the lithium secondary battery used therein must have a large capacity and a large output. For example, in an HEV, the lithium secondary battery for motor driving must have a high output because the motor assists the output of vehicle during acceleration. Since the voltage of a single battery is determined by the materials constituting the battery and, in the case of lithium secondary battery, is at best about 4.2 V in terms of open-circuit voltage and about 3 to 4 V in terms of actual discharge voltage, the above-mentioned "high output" means that a large current flows. In HEVs, etc., a large current of 100 A or more flows often and, in some cases, a current as large as 500 A flows in a short period of time.

The supported catalyst comprises ruthenium supported on a carbon black, called acetylene black, resulting from the pyrolysis of paraffin oils. Excerpt(s): The present invention relates to the hemihydrogenation of dinitriles to corresponding aminonitriles. The hydrogenation of dinitriles is generally carried out in order to prepare the corresponding diamines; thus, particularly, the hydrogenation of adiponitrile results in hexamethylenediamine, which is itself one of the base monomers in the preparation of polyamides. However, it can sometimes prove necessary to prepare not the diamine but the intermediate aminonitrile. This is the case, for example but not limitingly, in the hemihydrogenation of adiponitrile to aminocapronitrile, which is capable of subsequently being converted either to caprolactam, the base monomer in the manufacture of polyamide-6, or directly to polyamide-6.

Method for producing fluorinated diamond-like carbon films Inventor(s): Hakovirta; Marko J. (Geneva, CH), He; Xiao-Ming (Midland, MI), Lee; Deok-Hyung (Plano, TX), Nastasi; Michael A. (Santa Fe, NM) Assignee(s): The Regents of the University of California (Los Alamos, NM) Patent Number: 6,572,937 Date filed: November 30, 2000 Abstract: Fluorinated, diamond-like carbon (F-DLC) films are produced by a pulsed, glow-discharge plasma immersion ion processing procedure. The pulsed, glowdischarge plasma was generated at a pressure of 1 Pa from an acetylene (C.sub.2 H.sub.2) and hexafluoroethane (C.sub.2 F.sub.6) gas mixture, and the fluorinated, diamond-like carbon films were deposited on silicon <100>substrates. The film hardness and wear resistance were found to be strongly dependent on the fluorine content incorporated into the coatings. The hardness of the F-DLC films was found to decrease considerably when the fluorine content in the coatings reached about 20%. The contact angle of water on the F-DLC coatings was found to increase with increasing film fluorine content and to saturate at a level characteristic of polytetrafluoroethylene. Excerpt(s): The present invention relates generally to the deposition of diamond-like coatings on substrates and, more particularly, to the deposition of fluorinated diamondlike coatings on substrates using plasma immersion ion processing. Diamond-like carbon (DLC) films are known for their high hardness, wear resistance and low friction. Many applications have been developed for these coatings and their modified counterparts. A scratch resistant and extremely hard coating with excellent hydrophobic

(un-wetting) properties has numerous practical applications ranging from non-stick kitchenware to protective coatings for optics. Since DLC is itself only mildly hydrophobic, different elements such as F, N, O or Si, have often been incorporated into it by using a variety of techniques (see e.g., M. Grischke et al., Surf. Coat. Technol. 74, 739 (1995)). The fluorination of thin films and surfaces can be achieved using both etching and deposition treatments. However, the fluorine incorporation in surfaces after the widely used C.sub.2 F.sub.4 plasma etching process is only a few nanometers deep (see, e.g., Y. Lin and L. J. Overzet, Appl. Phys. Left. 62, 675 (1993) and C. Vivensang et al., Diamond Relat. Mater. 3, 645 (1994)), thereby limiting the applications of the treated surfaces. The deposition of different types of fluorinated films such as fluoropolymer films by sputtering of polytetrafluoroethylene (PTFE) onto targets or by using plasmaassisted deposition has been well established (see, e.g., D. Fleisch et al., J. Membrane Sci. 73, 163 (1992) and F. Quaranta et al., Appl. Phys. Lett. 63, 10 (1993)). For the plasma deposition of F-DLC films fluorocarbon-hydrocarbon mixtures have been mostly used (see, e.g., D. Fleisch et al., J. Membrane Sci. 73, 163 (1992), R. S. Butter et al., Thin Solid Films, 107 (1997), and J. Seth and S. V. Babu, Thin Solid Films 230, 90 (1993)). The results from various studies by different groups have shown that the un-wetting properties of F-DLC films can reach the performance of PTFE and the hardness and wear resistance have been kept relatively high (see, e.g., M. Grischke et al., Diam. Relet. Mater. 7, 454 (1998) and C. Donnet et al., Surf. Coat. Technol. 94-95, 531 (1997)). Earlier studies have also shown that the contact angle behavior of the F-DLC films produced with plasma techniques from fluorocarbon-hydrocarbon gas mixtures depends on the incorporation of CF.sub.2 and CF.sub.3 groups rather than CF group (see, e.g., D. Fleisch et al., supra, H. Kasai et al., J. Phys. D19, L225 (1986), and J. Seth and S. V. Babu, supra). This incorporation then depends on the composition of source gases, deposition technique and parameters and plasma chemistry that take place during the deposition. In order to attain widespread utilization, a method for deposition of thin films must be readily scalable to a production scale. This also applies to F-DLC films. To date, all plasma deposition techniques that have been used to produce hard F-DLC with good unwetting properties have been line-of-sight processes. Thus, complex-shaped objects are difficult to uniformly coat. Plasma Immersion Ion Processing (PIIP) for the deposition of F-DLC coatings differs from the Plasma Source Ion Implantation (PSII) process by employing a low pulsed-bias voltage, typically less than 10 kV, and enables the deposition of thin films on various substrate materials (see, e.g., K. C. Walter et al., Surf. Coat Technol. 93, 287 (1997) and S. M. Malik et al., J. Vac. Sci. Technol. A15, 2875 (1997)). Additionally, PIIP enables conformal deposition over large areas (see, e.g., J. R. Conrad et al., J. Appl. Phys. 62, 4591 (1987)). Web site: http://www.delphion.com/details?pn=US06572937__ •
Molding composition of siloxane capable of extending mold lifetime Inventor(s): Yang; Wen-Chen (No. 167, Pei Shing Street, Chia Yi, TW) Assignee(s): none reported Patent Number: 6,617,392 Date filed: January 3, 2002 Abstract: The present invention provides the molding composition of siloxane, which is capable of extending mold lifetime where inhibitors alkene or acetylene polymerization are mixed in the molds composed of siloxane. The inhibitors can effectively inhibit the release of alkene or acetylene when a resin containing an alkene or acetylene is poured

into the molds which extends lifetime of molds composed of siloxane. The inhibitors are compounds containing primarily sulfur, wherein sulfur is the most effective. Excerpt(s): The present invention provides a molding composition of siloxane which is capable of extending mold lifetime that can be realized by adding alkene or acetylene polymerization inhibitors into molds composed of siloxane and are especially indicated in this invention. The process of making molds (caves) by using solidificable composition of siloxane is primarily done by pouring the composition around objects which will be released and removed after the composition of siloxane solidify, then followed by emptying the caves where the objects were placed before are formed. The glassy or solid molded products will be obtained after the molded material, such as a liquid or resin with a solidifying agent, is added into the caves. The molded material most often used is a polymerizable liquid such as a polyester-styrene resin (unsaturated polyester resin) which will polymerize and solidify after it is injected into the mold caves composed of siloxane. However, since this process (especially for the alkene resin) is exothermic (sometimes highly exothermic reaction), the molds will be damaged after it is reused. 1. A part of a solidified composition of siloxane molds adhere to the molded material. The molds composed of siloxane are damaged by the pulling when the molded material is taken out. This is especially true for molds containing juts or fine stripes. Web site: http://www.delphion.com/details?pn=US06617392__ •
Olefin separations employing CTS molecular sieves Inventor(s): Bell; Valerie A. (Edison, NJ), Kuznicki; Steven M. (Whitehouse Station, NJ) Assignee(s): Engelhard Corporation (Iselin, NJ) Patent Number: 6,517,611 Date filed: July 23, 2001 Abstract: Separation of ethylene from ethane is achieved by feeding a mixture of the C.sub.2 hydrocarbons in contact with a CTS-1 crystalline titanium silicate molecular sieve which has a controlled pore size to selectively adsorb ethylene and size exclude ethane. The feed stream can also contain acetylene which can be selectively adsorbed from both ethane and ethylene by further controlling the pore size of the CTS-1 molecular sieve. Propane/propylene separation is also disclosed. Excerpt(s): This invention relates to use of adsorbents in purification of relatively impure olefins such as are typically produced by thermal cracking of suitable hydrocarbon feedstocks. More particularly, this invention concerns purification by passing an olefinic stream, containing alkanes, small amounts of acetylenic impurities, carbon oxides and/or other organic components, which are typically impurities in cracked gas oil, in contact with an adsorbent comprising a crystalline titanium silicate under conditions suitable for adsorption of olefins and/or alkynes. Generally, this invention is directed to separating useful alkenes (olefins) and/or alkynes from alkanes (paraffins) of the same carbon content and is more specifically directed to separating ethylene or propylene from mixed streams of ethane/ethylene or propane/propylene, respectively, using CTS titanium silicate adsorbents. As is well-known, olefins, or alkenes, are a homologous series of hydrocarbon compounds characterized by having a double bond of four shared electrons between two carbon atoms. The simplest member of the series, ethylene, is the largest volume organic chemical produced today. Importantly, olefins including ethylene, propylene and smaller amounts of butadiene,

Organic compound having an acetylene group, vacuum deposition polymerization thereof, deposited polymerized thin film, and electroluminescence device containing same Inventor(s): Jung; Sang Hyun (Taean-kun, KR), Kang; Yong Ku (Shinsung-dong, KR), Kim; Hee Jung (Myungjang-dong, KR), Lee; Chang Jin (Yusung-ku, KR), Lee; Sung Koo (Bundang-ku, KR) Assignee(s): Korea Research Institute of Chemical Technology (Daejeon, KR) Patent Number: 6,682,782 Date filed: January 3, 2001 Abstract: The present invention relates to an organic compound having acetylene group(s), a thin film formed by vacuum deposition polymerization using said organic compound, vacuum deposition polymerization to form said thin film, and an electroluminescence device containing said thin film. More particularly, the present invention relates to an organic compound having at least one acetylene groups, vacuum deposition polymerization in which said organic compound is deposited on the substrate and simultaneously or then polymerized by heat treatment or UV irradiation to form a polymer thin film, and an electroluminescence device using at least one layer of said thin film. Excerpt(s): Organic functional thin film is recently used in Thin Film Transistor-Liquid Crystal Device (TFT-LCD), organic polymer electroluminescence devices, piezoelectric devices, optical materials and the like because it is applicable for portable electronics. Conventional organic thin film can be prepared by wet process such as dip coating or spin coating but it has disadvantages in that a certain polymer which is insoluble in a solvent requires an additional process of coating a precursor and heating to form a thin film. Further, wet process. results in problems including easy contamination by a solvent, difficulty in controlling film thickness and film uniformity below 100 nm. Also wet process is not favorable for a following process such as a manufacturing process of semiconductors which requires dry process. On the other hand, a deposition polymerization is a method to produce an organic thin film by direct polymerization on the substrate by vaporizing a precursor with heat energy under high vacuum. Said deposition polymerization can i)produce a thin film through a simple vacuum device without using a catalyst or a solvent, ii)prevent from contamination of impurities, iii)control molecular sequences and film thickness, iv)provide easy preparing of a thin film of inprocessible polymer, and v)form a pattern by using a mask. Therefore, it is very important to develop thin film forming, technology by vacuum deposition polymerization which is expected to be essential to various electronic devices in future information industries.

(Westfield, NJ), Schulz; Donald N. (Annandale, NJ) Assignee(s): ExxonMobil Research and Engineering Company (Annandale, NJ) Patent Number: 6,541,586 Date filed: January 19, 1999 Abstract: The invention relates to a method of forming carbon monoxide-containing polymers from multi-component syngas feeds and at least one vinyl comonomer. Feeds useful in the practice of the invention comprise ethylene in an amount ranging from about 5 to about 40 mole %, carbon monoxide is an amount ranging from about 1 to about 40 mole %, hydrogen in an amount ranging from about 4 to about 55 mole %, carbon dioxide in an amount ranging from about 3 to about 10 mole %, and methane in an amount ranging from about 4 to about 85 mole %. The feed may also include acetylene in an amount ranging up to about 10 mole %. The feed may contain at least one free radical-polymerizable vinyl comonomer, or a cofeed containing such a comonomer can be used. Excerpt(s): The invention is directed towards a polymerization process for making copolymers from feeds of ethylene, carbon monoxide, and at least one vinyl comonomer, the feeds preferably being derived from hydrocarbon conversion processes. Ethylene copolymers with CO, and another vinyl comonomer are prepared at high pressure, high temperature from high purity monomer streams, especially streams having a low hydrogen concentration. Multicomponent syngas-type feeds, containing ethylene, carbon monoxide, hydrogen, carbon dioxide, and methane are formed from various gas conversion processes, and are becoming increasingly abundant. Using such feeds for polymerization would be beneficial. However, such feeds are not considered to have sufficient purity for polymerization because they contain substantial amounts of reactive species such as hydrogen and acetylene.

(Tokyo, JP) Patent Number: 6,506,946 Date filed: June 12, 2002 Abstract: The present invention provides a process for producing an acetylenediol continuously by reacting a ketone with acetylene in the presence of an alkali catalyst, which process comprises continuously feeding, into a first-stage reactor, a reaction solvent, an alkali catalyst, a ketone and acetylene to give rise to a reaction, continuously introducing the reaction mixture into a second-stage reactor, and continuously feeding a fresh portion of the same ketone into the second-stage reactor to give rise to a reaction. Excerpt(s): The present invention relates to a process for producing an acetylenediol continuously. More particularly, the present invention relates to a process for producing an acetylenediol continuously and efficiently by reacting a ketone with acetylene. An acetylenediol (hereinafter abbreviated to ADO in some cases) represented by, for example, the general formula (III) or (IV) shown below has been produced generally by reacting 2 moles of a ketone with 1 mole of acetylene in the presence of an alkali catalyst such as potassium hydroxide (see, for example, U.S. Pat. Nos. 2,385,546 and 2,455,058). In this reaction, however, not only ADO is produced but also an acetylenemonool (hereinafter abbreviated to AMO in some cases) which is a reaction product between 1 mole of the ketone and 1 mole of acetylene is formed as a by-product. Hence, it was attempted to minimize the amount of AMO formed as a by-product and increase the amount of ADO produced. In, for example, JP-A-63-258823, is disclosed a process for producing an alkynediol, wherein a particular ether type solvent and a particular ratio of raw materials are employed to suppress the amount of AMO formed as a by-product.

Acetylene
Process for selective hydrogenation of acetylene in an ethylene purification process Inventor(s): Blankenship; Steven A. (Radcliff, KY), Fried, Jr.; James E. (Buckner, KY), Perkins; Jennifer A. (Louisville, KY), Voight; Richard W. (Houston, TX) Assignee(s): Sud-Chemie Inc. (Louisville, KY) Patent Number: 6,509,292 Date filed: March 30, 2001 Abstract: A process for selective hydrogenation of acetylene during ethylene purification without in-situ prereduction utilizing a palladium/gold impregnated catalyst wherein the ratio of the gold to the palladium is from about 6:1 to about 50:1. Excerpt(s): This invention relates to a process for selective hydrogenation of acetylene in an olefinic feed stream, particularly for ethylene purification. This invention also relates to a catalyst, its process of preparation and its use for the selective hydrogenation of acetylene, particularly for ethylene purification. The manufacture of unsaturated hydrocarbons usually involves cracking various types of hydrocarbons and often produces a crude product containing hydrocarbon impurities that are more unsaturated than the desired product. These unsaturated hydrocarbon impurities are often very difficult to separate by fractionation from the desired product. A common example of this problem occurs with ethylene purification, in which acetylene is a common impurity. It is often difficult, industrially, to remove such undesirable, highly unsaturated hydrocarbons by hydrogenation without significant hydrogenation of the desired hydrocarbons. One example of this process is described in UK Pat. No. 916,056. Two general types of gas phase selective hydrogenation processes for removing undesired, unsaturated hydrocarbons have come into use. One, known as "front-end" hydrogenation, involves passing the crude gas from the initial cracking step, after removal of steam and condensible organic material, over a hydrogenation catalyst. Despite the large hydrogen content of such gas, which is very greatly in excess of the quantity of acetylenes that are present and which quantity should be sufficient to hydrogenate a substantial part of those acetylenes, substantially complete hydrogenation of acetylene with sufficient selectivity to produce olefins of polymerization quality is often a problem. The high concentration of hydrogen present in the front-end systems requires a very selective catalyst that does not substantially hydrogenate the ethylene. Overhydrogenation can lead to a thermal excursion in reactors, known as "run-away". Under "run-away" conditions, high temperatures are experienced, severe loss of ethylene occurs and catalyst damage takes place. In addition, furnace upsets in the front-end reactor system can result in swings of CO concentration from moderate levels to very low levels. Existing front-end catalysts cannot tolerate these swings in CO concentration very well and often are prone to "run-away". In the front-end reactor system, the catalyst is also exposed to high space velocity operations 10,000-12,000 GHSV per bed. In the other type of gas phase selective hydrogenation, known as "tail-end" hydrogenation, the crude gas is fractionated and the resulting concentrated product streams are individually reacted with hydrogen in a slight excess over the quantity required for hydrogenation of the highly unsaturated acetylenes which are present. However, in tail-end use there is a greater tendency for deactivation of the catalyst, and consequently, periodic regeneration of the catalyst is necessary. Tailend reactor systems operate at lower GHSV of 2500-5000 per bed. H2 addition can also be adjusted to maintain selectivity. However, formation of polymers is a major problem. Thermal excursion is not a problem. Web site: http://www.delphion.com/details?pn=US06509292__

This process is by preference used for the hydrogenation of phenyl acetylene in a styrene-containing medium which contains more that 30 wt. % of styrene. Excerpt(s): The invention relates to a process for the hydrogenation of phenyl acetylene in a styrene-containing medium with the aid of a catalyst and in the presence of hydrogen gas. Styrene is often polymerized to polystyrene. In the styrene-containing medium which is used for this purpose, the phenyl acetylene causes undesirable side reactions during the polymerization, such as cross-linking of the polymer chains.

Process for the purification and production of a diolefin hydrocarbon stream Inventor(s): Lankton; Steven P. (Wheeling, IL) Assignee(s): UOP LLC (Des Plaines, IL) Patent Number: 6,512,151 Date filed: April 18, 2001 Abstract: A selective acetylene hydrogenation process which is able to produce a high quality diolefin having extremely low levels of acetylene over an extended period of time compared with the prior art. The process of the present invention provides a selective hydrogenation reaction zone wherein the catalyst activity is maintained at a high level while the process unit remains on stream by contacting the selective hydrogenation catalyst with a polymer solvent, diolefin feed and hydrogen in one embodiment and by contacting the selective hydrogenation catalyst off-line with only polymer solvent and hydrogen in a second embodiment. In addition, the quantity of make-up regeneration solvent is significantly reduced. Excerpt(s): The field of art to which this invention pertains is the purification of a diolefin hydrocarbon stream containing trace quantities of acetylene compounds. The production of diolefins is well known and widely practiced to produce a wide variety of products and precursor products utilizing a variety of diolefin production processes including naphtha cracking processes and by-products from fluid catalytic cracking processes. Most of these diolefin production processes produce undesirable trace quantities of acetylene. One technique which is used to purify diolefin streams selectively hydrogenates the acetylene while minimizing the destruction or hydrogenation of the diolefin compounds. The selective hydrogenation of the acetylene

compounds is generally conducted in the presence of a selective hydrogenation catalyst and hydrogen and conducted at an elevated pressure and temperature. Such selective hydrogenation catalysts are well known in the art and include, for example, a catalyst containing copper metal associated with one or more activator metals impregnated on an alumina support. During the acetylene hydrogenation polymers are formed and deposited on the catalyst thereby reducing the activity of the catalyst. One known method of regenerating spent or partially spent catalyst is to perform a controlled carbon burn and subsequent metal reduction to remove catalyst contaminants which are formed as an undesirable by-product of the acetylene hydrogenation. The carbon burn regeneration techniques necessarily require that the reaction zone containing the spent catalyst be taken off-line and that ancillary regeneration equipment be provided. U.S. Pat.

According to the invention, the cooled dividing walls are formed by metal plates/metallic components in which hollow or intermediate spaces in the form of channels are provided in the metal plates/components for accommodating and conveying a cooling medium so as to cool the reactor. The reactor can be used for carrying out strongly exothermic catalytic reactions, for example for the selective hydrogenation of acetylene to ethylene. Excerpt(s): The invention relates to a reactor for carrying out reactions having a high enthalpy change containing catalyst particles between cooled dividing walls in at least one reactor vessel. Such a reactor is known from the journal Hydrocarbon Processing, March 1991, page 134. This is a multitube reactor with catalyst particles in the tubes. The tubes are cooled on the jacket side of the reactor by means of boiling water or other suitable heat-transfer media. The distribution of the reaction space and the catalyst particles over a plurality of tubes ensures that in the case of an operating fault any selfaccelerating reaction caused by local overheating is restricted to one reaction tube and does not encompass the entire reactor.

Water-soluble resin composition Inventor(s): Kanda; Takashi (Shizuoka, JP), Tanaka; Hatsuyuki (Shizuoka, JP) Assignee(s): Clariant Finance (BVI) Limited (Tortola, VG) Patent Number: 6,555,607 Date filed: February 28, 2001 Abstract: A water-soluble resin composition comprising (1) a water-soluble resin, (2) a water-soluble crosslinking agent, (3) at least one of surface active agents selected from acetylene alcohols, acetylene glycols, polyethoxylates of acetylene alcohols and polyethoxylates of acetylene glycols, and (4) a solvent consisting of water or a mixture of water and a water-soluble solvent. This water-soluble resin composition is applied onto a resist pattern, then heated to crosslink by an acid supplied from the resist, followed by development to remove the non-crosslinked water-soluble resin coating layer. This water-soluble resin composition is excellent in coating characteristics on steps of resist patterns and in dimensional regulation upon fining of patterns so that resist patterns such as trench patterns and hole patterns can effectively be fined. Excerpt(s): The present invention relates to a novel water-soluble resin composition and a fine pattern-forming material comprising the water-soluble resin composition. In particular, the present invention relates to a water-soluble resin composition which is coated on resist patterns formed and then crosslinked for thickening the resist patterns to fine effectively trench patterns or hole patterns and reduce the size of a space in the
54
Acetylene
resist patterns without investment in expensive facilities such as an exposure unit for short wavelengths or a phase-shift reticle in a process for producing semiconductor devices etc., and a fine pattern-forming material comprising said water-soluble resin composition. Photolithographic techniques has been traditionally used for the formation of fine elements or the fine processing in many fields such as the fabrication of semiconductor integrated circuits such as an LSI, the production of the display plane of a liquid crystal display device in an LCD panel, and the production of a circuit substrate for a thermal head and the like. To form resist patterns by photolithographic techniques, various positive- or negative-working radiation-sensitive resin compositions have been used. In recent years, as higher integration of semiconductor devices, the width of wires and separation gaps required in a production process become increasingly fine. To cope with this requirement, there are various attempts such as fining resist patterns with a light of shorter wavelength, forming fine resist patterns by means of a phase-shift reticle etc., and developing novel resists. In the conventional photolithographic techniques using exposure, however, formation of fine resist patterns exceeding the limit of wavelength is difficult, and exposure units for short wavelengths and devices using a phase-shift reticle are expensive. Accordingly, a method of forming fine patterns described below has been proposed. That is, after resist patterns are formed in a known method of forming patterns by using a known positive- or negative-working radiationsensitive resin composition, a coating layer is applied onto the resist patterns formed, and then the resist is heated and/or exposed to generate an acid to be diffused onto the coating layer. By the diffused acid, the coating layer is crosslinked to thicken the resist patterns, and as a result, gaps in the resist patterns are thinned. Thereby the resist patterns make fine and the fine resist patterns below the resolution limit are effectively formed. Various coating layer-forming compositions usable in the above method are known (e.g. JP-A Hei5-241348, JP-A Hei6-250379, JP-A Hei10-73927 etc.). As the composition for forming said coating layer, a water-soluble resin composition comprising a water-soluble resin, a water-soluble crosslinking agent and as necessary a plasticizer and a surface active agent and generating crosslinking reaction in the presence of an acid has been proposed. However, the conventionally known watersoluble resin composition is poor in the uniformity of coating film on steps of resist patterns and is accordingly poor also in the ability to regulate the dimension of patterns upon fining thereof. Therefore, there is demand for further development in respect of improvement of yield. Web site: http://www.delphion.com/details?pn=US06555607__

The invention includes filling a first tank to a first level, thereafter filling a second tank while continuing to fill the first tank. The invention further includes restricting the flow of gas to the second tank while continuing to fill the first tank. The invention also includes a first and a second transportable source of compressed acetylene. Excerpt(s): This application claims benefit of U.S. provisional patent application serial No. 60/404,028, filed Aug. 16, 2002, which is herein incorporated by reference. The present invention relates to a method and an apparatus for supplying compressed gas to a point of use. More particularly, the invention relates to an acetylene distribution system that fills a transportable source of gas that can be located at a worksite, used and then removed and replaced by another transportable source. Compressed fuel gases, especially gases such as acetylene, are well known and widely used in construction and manufacturing. Typically, acetylene is mixed with oxygen at a point of use to provide a combustible mixture. Because of its volatility, acetylene must be carefully handled before and during use. Conventionally, acetylene is provided at a point of use in a cylinder that can be delivered and then removed and refilled. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Acetylene polymers and their use as liquid crystals Inventor(s): Kong, Xiangxing; (Hong Kong, HK), Kwok, Hoi Sing; (Hong Kong, HK), Lam, Wing Yip; (Hong Kong, HK), Tang, Ben Zhong; (Hong Kong, HK) Correspondence: Burns, Doane, Swecker & Mathis, L.L.P.; P.O. Box 1404; Alexandria; VA; 22313-1404; US Patent Application Number: 20030164474 Date filed: January 17, 2003 Abstract: There is disclosed a liquid crystalline polyacetylene having a repeat structure of the formula 1where spa is a spacer group and mes is a mesogenic substituent. Excerpt(s): The present invention relates to novel classes of mesogen containing acetylene polymers with particular, but by no means exclusive, reference to their use as liquid crystals. The present invention also relates to novel classes of mesogen containing acetylene monomers, and to polymerisation methods for producing said polymers from said monomers. Most industrially utilised plastics consist of polymers having flexible chains. In contrast, polymers having relatively rigid polymeric chains have proven far less useful in an industrial context, primarily due to processing difficulties associated with their low solubility and high melting temperature. This is despite the fact that rigid polymers can exhibit some very interesting properties. For example, polyacetylene and
56
Acetylene
associated derivatives thereof can exhibit electrical conductivity (when doped), chemical reactivity and complex forming ability. Another potential application is chiral separation. However, polyacetylene is completely intractable, insoluble and infusible, and has found few practical applications. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Aqueous ink composition Inventor(s): Momose, Masayuki; (Nagano-ken, JP) Correspondence: Ladas & Parry; 26 West 61 Street; New York; NY; 10023; US Patent Application Number: 20030101905 Date filed: April 4, 2002 Abstract: An aqueous ink composition comprising at least: a colorant; water; 0.005 to 10 wt. %, based on the whole weight of the ink composition, of at least one acetylene alcohol compound represented by the following formula (1): 1wherein R.sub.1, R.sub.2 and R.sub.3 each independently represents a hydrogen atom, an alkyl group which may be branched, or an alkylphenyl group; and a surface active substance capable of causing the acetylene alcohol compound of formula (1) to dissolve in water. Excerpt(s): The present invention relates to aqueous ink compositions, particularly to quick-drying type aqueous ink compositions suitable for ink jet printing method. It has bee the common practice to add, to aqueous ink compositions, a surface active substance in order to (a) improve print quality (including adaptability to paper), (b) improve quick drying property and (c) prevent bleeding between adjacent colors upon multi-color printing. Since a surface active substance to be added to aqueous ink compositions is required to have high penetration promoting effects into a recording medium and structural characteristic that does not cause defects such as bubbling during printing, a nonionic surfactant is often selected as the surface active substance. Particularly, surfactants such as acetylene alcohol compounds and acetylene glycol compounds have attracted attentions as surfactants capable of satisfying the above-described requirements. Among them, acetylene alcohol compounds have markedly high penetration promoting effects and they are known to provide excellent print quality even with a small addition amount (for example, Japanese Patent Laid-Open No. 139964/1988, Japanese Patent Laid-Open No. 239068/1992).

the ink liquid medium at 40.degree. C. to its dissolution amount (A) in the ink liquid medium at 25.degree. C. (A) of from 1 to 10. Excerpt(s): The present invention relates to an aqueous ink composition containing a pigment as a colorant and to a process for ink jet recording with the ink composition. The invention further relates to an aqueous ink composition containing an aqueous dispersion of pigment-containing polymer particles and to a process for ink jet recording with the ink composition. Solvent-based inks have problems concerning influences of the organic solvents on the global environment and working atmosphere, and aqueous inks have hence come to be mainly used. Water-soluble dyes have been used in inks for water-base writing utensils and ink jet printers. However, water-soluble dyes intrinsically have poor resistance to light and gases and, hence, use of the dyes has a drawback concerning the storability of recorded images. Namely, when recorded images are exposed to light such as sunlight or the light of a fluorescent lamp, the watersoluble dyes undergo color fading to impair the image quality. Furthermore, the watersoluble dyes suffer color fading by the action of oxidant gases contained in the air, e.g., ozone, to impair the image quality. Water-soluble dyes further have a problem concerning water resistance. For overcoming those problems, aqueous inks employing a pigment as a colorant are recently being investigated.

use different sources of calcium carbide as well as the calcium carbide manufacturers to use different sources of raw materials to make calcium carbide. Excerpt(s): This invention relates to a composition for use in the production of acetylene gas and a method for treating the lime slurry by-product from acetylene gas production to make the slurry easier to handle and avoid the need for special handling equipment for the sediment. The present invention allows an acetylene producer to use calcium carbide from a variety of sources and allows the calcium carbide producer more flexibility in sourcing raw materials. Calcium carbide (CaC.sub.2) is produced in an electric furnace by heating a mixture of lime and carbonaceous materials such as coke, coal, or charcoal. The heat of the furnace converts the mixture to calcium carbide and carbon monoxide. Both the source of lime and the source of carbonaceous material have different impurities which are carried through to the calcium carbide. Typically, industrial grade calcium carbide, sold for the generation of acetylene gas, contains about 2% to about 5% by weight impurities. The primary impurities are metals and metal alloys such as silicon, iron, aluminum and magnesium. One of the conventional methods for producing acetylene (CH.ident.CH) is the action of water on calcium carbide. One of the by-products from such production is a lime slurry. This lime slurry essentially comprises calcium hydroxide, water, and whatever impurities were present in the calcium carbide. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

C. and from 0.11 to 5 MPa absolute comprises continuously feeding the corresponding OH, SH or NH compound and the acetylene and operating at a conversion of the corresponding OH, SH or NH compound of.gtoreq.90%. Excerpt(s): The present invention relates to a continuous process for the preparation of O--, S-- and N-alkenyl compounds by reaction of the corresponding OH, SH or NH compound with an acetylene in the liquid phase in the presence of basic alkali or alkaline earth metal compounds at from 40 to 300.degree. C. and from 0.11 to 5 MPa absolute. Alkenyl compounds represent an important class of compound with a wide range of applications. Alkenyl ethers, for instance, find use as monomeric building blocks in polymers and copolymers, in coatings, adhesives, printing inks and also in radiation-curable coatings. Further areas of application are the production of intermediates, scent and aroma chemicals, and also pharmaceutical products. Alkenylamides are used as monomers in the production of plastics and coatings. Polyvinylamides are used, for example, as laundry detergent ingredients, as adjuvants in cosmetic and medicinal products and also to stabilize and clarify beers and fruit

juices. Polyvinyllactams, in particular polyvinylpyrrolidone polymers, have a wide range of uses and serve, for example, as dispersants for pigments, as laundry detergent ingredients, as adjuvants in cosmetic and medicinal products and also as assistants in textile processing and adhesive technology. The industrial production of vinyl compounds is carried out in general by reaction of the corresponding active-hydrogen compounds, such as alcohols, amides or amines, with ethyne in the presence of basic catalysts (see Ullmann's Encyclopedia of Industrial Chemistry, 6.sup.th edition, 2000 Electronic Release, Chapter "VINYL ETHERS--Production" and W. Reppe et al., Justus Liebigs Ann. Chem., 601 (1956), pages 135 to 138). The vinylation can take place in both the liquid phase and the gas phase. Vinylation in the gas phase employs basic heterogeneous catalysts, such as KOH on activated carbon or MgO or CaO. In the liquid phase, the strongly exothermic reaction is generally carried out in the presence of alkali metal hydroxide or alkali metal alkoxide catalysts.

Acetylene
Abstract: There is disclosed a dampening composition for lithographic printing which comprises a (poly) propylene glycol alkyl ether and an ethylene oxide adduct of acetylene glycol. Excerpt(s): This invention relates to a dampening composition for lithographic printing, more specifically to a dampening composition to be preferably used in lithographic printing using ink containing soybean oil, further to a dampening composition suitable for printing using a lithographic printing plate which utilizes a light-sensitive silver halide. Lithographic printing is a printing system which adroitly utilizes characteristics in which water and oil do not inherently mix to each other. A lithographic printing plate comprises oleophilic image portions which are receptive to oily inks and oil-repellent non-image portions which are not receptive to the inks. In general, said non-image portions are receptive to water, namely, hydrophilic. Usual lithographic printing is carried out by feeding both ink and a dampening solution to the surface of printing plates to allow the image portions to receive preferentially the coloring ink and the nonimage portions to receive preferentially the dampening solution and, then, transferring the ink on the image portions onto a substrate such as paper. In such a lithographic printing, it is important that inks and the dampening solutions are fed onto the lithographic plate with a suitable balance. If an amount of the dampening solution to be fed onto the lithographic plate is too little, there is a problem that ink stain occurs at the non-image portions while if an amount of the dampening solution is too much, emulsification of the ink excessively proceeds whereby a density at the image portions becomes insufficient. In a conventionally known dampening solution, there is a solution in which a hydrophilic agent such as phosphoric acid or a salt thereof, Gum Arabic, carboxymethyl cellulose (CMC) and the like are contained. These dampening solutions containing these compounds, however, involve a problem that they do not uniformly wet at the non-image portions, so that they are insufficient for the characteristics of a dampening solution used for high speed printing in recent years.

of forming ceramic sheets involve dissolving a binder such as polyvinyl butyral resin in an organic solvent, admixing a finely divided ceramic raw material in the solution, and milling the mixture in a ball mill or suitable mixer for a long time for dispersion. After defoaming, the dispersion is applied to a film support of polyester or the like to a certain thickness to form a green sheet, which is fired. Because of the flammability and environmental problems of organic solvents, it was recently proposed to use aqueous binders to avoid the use of organic solvents. Water-soluble binders including polyvinyl alcohol and water-soluble polyurethane were developed as disclosed in JP-A 60-180955. They have found more frequent use.

C. and 3000.degree. C. The carbon nanotubes range from 4 to 500 nm in diameter and 0.1 to 50.mu.m in length depending on growth conditions. Carbon nanotube density can exceed 10.sup.4 nanotubes/mm.sup.2. Acetylene is used as the carbon source gas, and ammonia is used as the catalyst gas. Plasma intensity, carbon source gas to catalyst gas ratio and their flow rates, catalyst film thickness, and temperature of chemical vapor deposition affect the lengths, diameters, density, and uniformity of the carbon nanotubes. The carbon nanotubes of the present invention are useful in electrochemical applications as well as in electron emission, structural composite, material storage, and microelectrode applications. Excerpt(s): This application claims the benefit of U.S. Provisional Patent Application Serial No. 60/089,965, filed Jun. 19, 1998, and U.S. Provisional Patent Application Serial No. 60/099,708, filed Sep. 10, 1998. The present invention relates to a product with a substrate having one or more carbon nanotubes, a method of producing that product, and devices utilizing the product. Since the first observation of carbon nanotubes, numerous papers have reported studies on the yield of well-graphitized nanotubes, their diameter and wall thickness (single or multiple), growth mechanisms, alignment, electron emission properties, nanodevices, theoretical predictions, and potential applications. Selective positioning and growth of carbon nanotubes is necessary for future integration with conventional microelectronics as well as the development of novel devices. However, limited progress has been reported in the controlled placement of nanotubes. Alignment of the carbon nanotubes is particularly important to enable both fundamental studies and applications, such as cold-cathode flat panel displays, chargeable batteries, and vacuum microelectronics.

substance whose structure is shown by formula (IA) according to claim 2, a substance whose structure is shown by formula (I) according to claim 20, or the like), and a nonionic substance that has lipophilic units comprising alkyl groups or cycloalkyl groups and that also has alkylene oxide repeating structures (preferably a substance whose structure is shown by formula (IIA) according to claim 2, a substance whose structure is shown by formula (II) according to claim 20, or the like). Excerpt(s): The present invention relates to an inkjet ink capable of providing high print quality on plain paper, recycled paper, or coated paper. The present invention relates to an inkjet ink capable of ensuring high ejection stability and providing high print quality on plain paper, recycled paper, or coated paper. Inkjet recording is a method in which ink is ejected as droplets from minute nozzles to record characters and patterns on the surface of a recording medium. The inkjet recording systems used include methods in which electric signals are converted to mechanical signals with the aid of an electrostrictive element, and ink stored in a nozzle head portion is continuously ejected to record characters or symbols on the surface of a recording medium; and methods in which ink stored in a nozzle head portion is foamed by the rapid heating of the part that is the closest to the ejection portion, discontinuously ejected by foaming-induced volumetric expansion, and used to record characters or symbols on the surface of a recording medium. The ink used for such inkjet recording must ensure good print drying, no print bleeding, uniform printing on the surface of the recording medium, no blending of colors in the case of multicolor printing, and other characteristics. A particular problem in this case is that bleeding can be easily caused by fibers that have different permeability levels when paper is used as the recording medium.

Excerpt(s): The present invention relates to an ink jet recording ink, an ink jet recording ink set, a recording method, recorded matter, and an ink jet recording apparatus. Ink for such ink jet recording is required to have various specific characteristics. For example, for printing on paper which is an recording object, the requirements of the ink to be used are that it does not cause bleeding, it quickly dries thereon, it enables uniform recording on various kinds of recording objects, and it does not mix with the neighboring ink in multi-color printing to form color prints. For ink jet recording ink, generally used are those prepared by dissolving various kinds of water-soluble dyes in aqueous media. Recently, those prepared by dispersing pigments in aqueous media have been provided, and this is characterized in that the pigment-containing inks are superior to the water-soluble dye-containing ones in water-resistance and lightresistance.

Long-term fertilizer containing nitrogen Inventor(s): Czikkely, Vilmos; (Mannheim, DE), Hahndel, Reinhard; (Limburgerhof, DE), Horchler, Klaus; (Limburgerhof, DE), Weigelt, Wolfgang; (Dudenhofen, DE), Wissemeier, Alexander; (Speyer, DE), Zerulla, Wolfram; (St. Martin, DE) Correspondence: Collard & Roe, P.C.; 1077 Northern Boulevard; Roslyn; NY; 115761696; US Patent Application Number: 20030154755 Date filed: December 6, 2002 Abstract: A long-term fertilizer containing nitrogen, contains a mixture of acetylene diurea and at least one other organic fertilizer containing nitrogen, such as methylene urea, isobutylidene diurea, crotonylidene diurea, oxamide, melamine, substituted triazones, ethylene diurea, triuret or mixtures of them. Excerpt(s): The present invention relates to long-term fertilizers containing nitrogen, methods for their production, and their use. Fertilizers with a long-term effect have many advantages as compared with conventional mineral or organic fertilizers. They offer a delivery of the nutrients to the plants that is better in keeping with demand, and thereby improve the utilization of the nutrients. This results in a reduction of nutrient losses, thereby reducing the burden on the environment and increasing the efficiency of fertilization. In addition, they make it possible to save work steps and thereby to reduce agriculture business costs. A long-term effect of fertilizers can be achieved in different ways. One possibility is to surround granulated fertilizers that are easily soluble in water with a coating that is insoluble in water. Nutrient release from such coated fertilizers takes place with a time delay, since the nutrients first have to diffuse through the coating layer, before they can be taken up by the roots. Another possibility is to apply the fertilizers initially in the form of chemical compounds in which they are not available to the plants. Only after a prior release step has taken place, e.g. chemical hydrolysis, enzymatic splitting and/or microbial conversion, are the nutrients present in a form that can be utilized by the plants. Such fertilizers are also referred to as chemical long-term fertilizers. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Low-pressure carburising method Inventor(s): Goldsteinas, Aymeric; (Voreppe, FR), Pelissier, Laurent; (Saint Jean de Moirans, FR) Correspondence: Duane Morris Llp; 100 College Road West, Suite 100; Princeton; NJ; 08540-6604; US Patent Application Number: 20030168125 Date filed: May 6, 2003 Abstract: The invention relates to a low-pressure carburising method comprising alternating low-pressure enrichment steps and diffusion steps in the presence of a neutral gas. During the enrichment steps, an enriching gas and neutral gas mixture is used, the proportion of the neutral gas being between 5 and 50% by volume of the enriching gas. The enriching gas can be, for example, acetylene (C.sub.2H.sub.2). Excerpt(s): The present invention relates to the processing of metal parts and more specifically to cementation, that is, the introduction of carbon down to a given depth of the parts to improve their mechanical features. A specific low-pressure cementation method has already been described in French patent no 2678287 of the applicant (inventor: Jean Naudot). This patent provides alternating enrichment steps and diffusion steps. It specifies that the cementation gas may be any hydrocarbon capable of dissociating at work temperatures to cement the parts to be processed. However, this method more specifically provides using propane as the cementation gas and nitrogen as the neutral gas between cementation phases. Further, an article by Jelle H. Kaspersma and Robert H. Shay published in Metallurgical Transactions, volume 13B, Jun. 1982, studies the cementation speeds linked to the use of various enrichment gases and the soot formation problems. It indicates that acetylene is the gas enabling the fastest cementation, but with the disadvantage of generating the most soot in the processing chamber.

Method and apparatus for lubricating molten glass forming molds Inventor(s): Burton, Robert L.; (Maumee, OH), Leidy, D. Wayne; (Perrysburg, OH), Newsom, Daniel L.; (Oak Harbor, OH), Scott, Garrett L.; (Toledo, OH) Correspondence: Nirav D. Parikh; Owens-illinois, INC.; One Seagate, 25-ldp; Toledo; OH; 43666; US Patent Application Number: 20030221455 Date filed: May 28, 2002 Abstract: A burner (16, 116, 216) of a nozzle-mixing type receives a carbonaceous fuel, for example, an acetylene-based fuel, from a fuel line (20) and an oxidant, such as relatively pure oxygen, from an oxidant line (18), the oxidant being supplied to the burner at a rate insufficient to result in complete combustion of the fuel, to thereby produced a sooty flame that is useful in applying lubricating soot particles to a molten glass contacting surface of a glass manufacturing machine. The burner, which is intermittently operated by a solenoid valve (38) in the oxidant line and by a solenoid valve (40) in the fuel line, has a fuel inlet passage (60) that extends along a longitudinal central axis of a tip element (56) of the burner, and an annular inlet passage (64) that surrounds the fuel inlet passage. The fuel inlet passage, which is otherwise closed at its downstream end, terminates in a multiplicity of separate passages (62) that are arranged in an annular array and through which fuel exits from a burner tip in an annular pattern on an interior of oxidant exiting from the burner in an annular pattern through a passage (66) in an annulus between the tip element and a cap element (58) of the burner. The burner serves to ensure rapid mixing of the fuel and oxidant streams downstream of the burner, to thereby rapidly form an ignitable mixture that can be ignited by a spark igniter (54) 2-way solenoid valves (38, 40) are provided in the oxidant and fuel lines, respectively, to permit the burner to be operated intermittently. Excerpt(s): This invention relates to a method and an apparatus for lubricating the molten glass contacting surfaces of glass forming molds. More particularly, this invention relates to a method and apparatus of the foregoing character for imparting a layer of carbon soot derived from the partial oxidation of a gas that contains acetylene, such as mapp gas (a mixture of methyl acetylene and propadiene). As is known, for example, from U.S. Pat. No. 5,958,099 (Moreftin) or U.S. Pat. No. 5,679,409 (Seeman), it is desirable to lubricate a molten glass contacting surface of a glass manufacturing machine, for example, an internal surface of a forming mold of such a machine, with a thin layer of carbon soot as a substitute for periodically brushing such a surface with a conventional oil and graphite-based mold dopant. Such a soot coating is obtained by the partial oxidation of a carbonaceous gas, such as acetylene or a mixture of an acetylenebased gas, such as methacetylene and propadiene (occasionally referred to as mapp gas or as MAPD gas) by way of a burner whose flame is directed towards the mold surface to be coated. The aforesaid Seeman '409 patent describes a mold surface
Patents 69
soot-coating system in which a mixture of MAPD gas and oxygen, after igniting by a natural gas-derived pilot flame, is directed toward a surface to be coated. As noted in Seaman '409, because of the inherently intermittent nature of the operation of a soot burner in a glass manufacturing machine, a mixture of MAPD gas and oxygen must be carefully controlled so as to prevent backfiring of the flame from the burner into the burner nozzle (column 3, lines 9-20), and it is understood that the system of the Seeman '409 patent has proven to be capable of operating in a successful manner in sooting glass-making molds of a Hartford 28 rotary tableware glass forming machine, where a single sooting burner can service all molds on a rotating table. In that regard, the pulse rate of a sooting burner for a Hartford 28 tableware machine occurs at a fairly high frequency, and any tendency of backfiring to occur by the backflow of oxygen into the fuel line through an air-fuel mixer can be avoided by careful control of the operating condition of the sooting apparatus.

Method for making an extreme ultraviolet microlithography tranmission modulator and resulting modulator Inventor(s): Arnal, Yves Alban Marie; (Poisat, FR), Golanski, Andre; (Pologne, FR), Lacoste, Ana; (St. Martin Le Vinoux, FR), Pelletier, Jacques Henri,Lucien; (St. Martin D'Heres, FR), Piazza, Fabrice; (Saint Die, FR) Correspondence: Young & Thompson; 745 South 23rd Street 2nd Floor; Arlington; VA; 22202 Patent Application Number: 20040052971 Date filed: September 11, 2003 Abstract: The invention concerns a method for making an extreme ultraviolet microlithography transmission modulator, characterised in that it consists in obtaining adamantine amorphous carbon by a process using a plasma consisting of a mixture of acetylene and argon and maintained by the power of a microwave source; in depositing a thin adamantine amorphous carbon film on a substrate with low absorption in extreme ultraviolet whereto is applied a variable polarisation; in varying the forbidden band between 1 and 2 eV through control of the argon partial pressure and in varying the corresponding extinction coefficient so as to modulate the modulator transmission without modifying the thickness of the deposited film. Excerpt(s): The present invention relates to the production of transmission and phase modulators for deep ultraviolet microlithography, and relates more particularly to the production of transmission modulators with variable transmission aperture for deep ultraviolet microlithography (157 nm). The methods and the materials which are currently used in microlithography at 248 nm cannot be used in deep UV: for wavelengths less than 193 nm, the absorption coefficients of the materials are much too high. Considerable effort is being directed at present to developing new materials which can be used in deep UV. Adamantine amorphous carbon (DLC) is amongst the new materials proposed for the applications in deep ultraviolet microlithography. The technique recently proposed by Lucent Technologies enables production of the transmission modulators from DLC. DLC is an absorbent material, such that the transmission can be modulated by varying the thickness of the layer of DLC. The principal limitation of the Lucent Technologies technique comes from the intrinsic stress which is always present in DLC. The stress increases with the thickness and can lead to

delamination or destruction of the film. The presence of the stress limits the thickness of the film and the corresponding attenuation of the transmission. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Method for separation and recovery of propargyl alcohol Inventor(s): Fukuda, Hideo; (Ichihara-shi, JP), Omori, Hideki; (Ichihara-shi, JP), Sato, Tomohiko; (Ichihara-shi, JP), Sawada, Goro; (Ichihara-shi, JP), Takeuchi, Mitsuru; (Ichihara-shi, JP) Correspondence: Melvin L Stoltz; 51 Cherry Street; Milford; CT; 06460; US Patent Application Number: 20030109757 Date filed: November 8, 2002 Abstract: The present invention provides a method for separating and recovering propargyl alcohol from a product mixture containing a solvent, water and propargyl alcohol, which alleviates the problems of prior art and which can separate and recover propargyl alcohol in a simple operation at an advantageous thermal energy without requiring a large distillation unit or a complicated separation operation or step.The method for separation and recovery of propargyl alcohol according to the present invention is characterized by subjecting, to distillation at a pressure of 100 to 150 mmHg, a propargyl alcohol-containing product mixture obtained by reacting paraformaldehyde with acetylene in the presence of a catalyst in a polar solvent. Excerpt(s): The present invention relates to a method for separating and recovering propargyl alcohol from a product mixture containing propargyl alcohol obtained by a reaction between paraformaldehyde and acetylene, particularly to a method for simply and efficiently separating propargyl alcohol from the solvent, etc. used in the reaction. For example of a synthesis of propargyl alcohol, a method which comprises subjecting an aldehyde or a ketone to a reaction with an acetylene type hydrocarbon in a particular solvent, in the presence of an alkali metal oxide or an alkali metal alcoholate as a catalyst, is known (U.S. Pat. No. 2,996,552). The product mixture after the reaction contains a large amount of the polar solvent and water which is contained in the raw materials or formed by the reaction; therefore, their separation from propargyl alcohol is necessary. However, it is not generally easy to separate propargyl alcohol of high polarity from the solvent of high polarity and water, by means of a distillation or the like and, particularly when the difference in boiling point between the solvent and propargyl alcohol is small, their separation is more difficult. Hence, in order to separate propargyl alcohol, for example, a method which comprises adding fresh water of which separation inherently is difficult, to the product mixture and subjecting the resulting mixture to distillation to separate an azeotropic mixture of propargyl alcohol and water from the solvent, and a method which comprises adding a solvent showing azeotropy with water and subjecting the mixture to distillation to separate and recover propargyl alcohol, have hitherto been employed (U.S. Pat. No. 3,097,147). With such methods, however, it is apparent that a large distillation unit is required, the steps of distillation and separation are complicated, and there is a disadvantage in thermal energy.

Method for the continuous production of acetylene diurea Inventor(s): Czikkely, Vilmos; (Mannheim, DE), Franke, Dirk; (Birkenheide, DE), Horchler, Klaus; (Limburgerhof, DE) Correspondence: Collard & Roe, P.C.; 1077 Northern Boulevard; Roslyn; NY; 115761696; US Patent Application Number: 20040054191 Date filed: July 7, 2003 Abstract: The continuous production of acetylene diurea takes place by means of the reaction of glyoxal with urea in the presence of mineral acids. The reaction is carried out in at least one reactor having a mixing device, into which glyoxal, urea, and mineral acid are continuously fed, and from which a suspension of acetylene diurea in mother liquor is discharged. The acetylene diurea is mechanically removed from the mother liquor, and the remaining mother liquor is recycled back into the reactor, in whole or in part. Excerpt(s): The present invention relates to a method for the continuous production of the time-release nitrogen fertilizer acetylene diurea. Fertilizers with a time-release effect have many advantages as compared with conventional mineral or organic fertilizers. They offer a delivery of nutrients to the plants that is better in keeping with the plants' needs, and thereby improve the utilization of the nutrients. This results in a reduction in nutrient losses, thereby reducing the burden on the environment and increasing the efficiency of fertilizer use. In addition, they make it possible to save work cycles and operating materials, and thereby agricultural costs. A time-release effect of fertilizers can be achieved in different ways. One possibility is to surround granulated fertilizers that are easily soluble in water with a covering that is insoluble in water. The nutrient release from such coated fertilizers takes place with a delay, since the nutrients must first diffuse through the cover layer before they can be absorbed by the roots. Another possibility is to apply the nutrients in the form of chemical compounds in which they are not available to the plants at first. Only after a prior release step, for example chemical hydrolysis, enzymatic splitting and/or microbial transformation, has taken place, will the nutrients be available in a form that the plants, can utilize. Such fertilizers are also called chemical time-release fertilizers. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Excerpt(s): This application is a continuation-in-part application of pending U.S. patent application Ser. No. 08/818,193 filed on Mar. 14, 1997. This invention relates to a new class of transition metal containing linear polymers of varying molecular weight that are useful for conversion to high temperature thermosets and ceramics. These new materials have repeat units that contain alkynyl groups for cross-linking purposes along with organotransition metal complexes, silyl, siloxyl, boranyl, or di(silyl or siloxyl)carborane units. These novel linear polymers with the metal units in the backbone are soluble in most organic solvents and can be easily fabricated from the melt into shaped components, which enhance their importance for high temperature structural, magnetic, and microelectronic applications. Cross-linking of alkynyl groups is known to occur by either photochemical or thermal processes. The ceramics may also contain carbon nanotubes and/or metal nanoparticles. The incorporation of transition metals into a polymer structure has long been seen as a good way of preparing materials with different properties from conventional carbon-based polymers. Small molecule transition metal complexes and solid state compounds possess an array of interesting high temperature, hardness, redox, magnetic, optical, electrical, and catalytic properties. In addition, the rich diversity of coordination numbers and geometries available for transition elements offer the possibility of accessing polymers with unusual conformational, mechanical, and morphological characteristics.

Acetylene
Abstract: Presented is an improvement to a previous invention involving the catalytic hydrogenation of the C.sub.2 to C.sub.5 and heavier acetylenes and dienes in a thermally cracked feed stream without significantly hydrogenating the C.sub.2 and C.sub.3 olefins. The improvement involves the use of a fixed bed hydrogenation reactor system in combination with a modified version of the catalytic distillation unit used in the prior art. The modification to the catalytic distillation unit involves improvement of the liquid recycle scheme. The fixed bed reactors combined with the modified catalytic distillation allows for 100% conversion of acetylene and helps to maintain high conversion of the other dienes and acetylenes with no ethylene or propylene conversion under a variety of conditions. These condition variations include but are not limited to the feed diene and acetylene composition, the mol % carbon monoxide in the feed, and catalyst deactivation. With catalytic distillation alone, complete conversion of the acetylene as stated above can not be achieved without ethylene loss, nor would satisfactory operation and control be possible under the variety of conditions experienced during a commercial operation. Excerpt(s): The present invention relates to a method for the production of olefins and particularly to processing the cracking heater effluent to more effectively recover the product and process the by-products. In the production of ethylene and propylene through the pyrolysis of a variety of feedstocks, several byproducts and unsaturated diolefins and acetylenes are created. The net effluent from the pyrolysis heaters, typically referred to as charge gas, requires processing for the separation of the byproducts and removal of the diolefins and acetylenes from the primary olefin products. Removal of the C.sub.2 and heavier diolefins and acetylenics from the cracked gas is handled through a combination of separation via distillation and reaction via hydrogenation. Specifically for acetylene, separation alone would result in excessive loss of the ethylene product since acetylene and ethylene have very similar relative volatility. Currently, the distillation and hydrogenation take place in several distinct process steps that are designed to separate and hydrogenate the C.sub.2, C.sub.3, and C.sub.4 compounds independently. Separation of the different hydrocarbons before hydrogenation is currently required for achieving better control over the hydrogenation, prolonging catalyst life, and enhancing performance. One disadvantage of this widely practiced conventional technology is the large energy consumption necessary to generate the high pressures and cryogenic temperatures required to separate first the hydrogen from the cracked gas and then subsequently the molecules of higher carbon number.

An optically active,
Patents 75
hydrogen phosphinic acid ester is reacted with an acetylene compound in the presence of a catalyst containing a metal of group 9 or 10 of the periodic table to thereby obtain a novel, optically active alkenylphosphinic acid ester which has chirality on a phosphorus atom and is represented by the following general formula [1] and/or [2].R.sup.1{CH.dbd.CR.sup.2[P(O)(OR.sup.3)Ar]}.sub.n [1]R.sup.1{C[P(O)(OR.sup.3)Ar].dbd.CHR.sup.2}.sub.n [2] Excerpt(s): The present invention relates to a novel optically active alkenylphosphinic acid ester compound having chirality on a phosphorus atom and to a process for producing the same. With regard to optically active alkenylphosphinic acid esters, their fundamental skeleton has been found in nature and it has been known that they themselves show a physiological activity when made to act with enzyme or the like. Further, the compounds are very useful. For instance, they can easily be converted to optically active tertiary phosphines, which are widely used as auxiliary ligands for various kinds of asymmetric catalytic reactions. Furthermore, the compounds easily react with nucleophilic agents and radical species and are able to be used for HornerWittig reaction. Thus, they are a group of compounds highly useful in view of synthesis of fine chemicals as well. General synthetic method for optically active alkenylphosphinic acid esters has not been known yet. With regard to a method for their synthesis involving the formation of the carbon-phosphorus bond, one can consider a method where the corresponding alkenyl halide compound is subjected to the substitution reaction with hydrogen phosphinic acid ester. However, in that method, it is necessary to add a base for trapping the hydrogen halide which is simultaneously produced as a result of the reaction, and hence large quantities of hydrogen halide salt are produced as well. In addition, alkenyl halide compounds, which are the starting materials, are not always easily available on the basis of industry and, further, they are usually toxic. Therefore, this method is not industrially advantageous at all. There is another method where racemic alkenylphosphinic acid esters are subjected to optical resolution but the process involved in the optical resolution is generally troublesome whereby it is not an industrially advantageous manufacturing method as well.

Oxygenate conversion in the presence of highly unsaturated compounds Inventor(s): Ou, John Di-Yi; (Houston, TX), Risch, Michael A.; (Seabrook, TX) Correspondence: Exxonmobil Chemical Company; Law Technology; P.O. Box 2149; Baytown; TX; 77522-2149; US Patent Application Number: 20040097760 Date filed: November 15, 2002 Abstract: The present invention provides a process for treating a stream, say, an olefins stream, e.g., propylene, containing at least one ether, e.g., dimethyl ether, and/or at least one of an alkyne and an alkadiene, e.g., methyl acetylene and propadiene, typically present as impurities. The process comprises: contacting the stream with a metalcontaining catalyst, e.g., palladium supported on alumina, under conditions sufficient to convert the ether and the at least one of an alkyne and an alkadiene to provide a product stream having a reduced impurities content. Excerpt(s): The present invention relates to a method for treating streams in the presence of oxygenates, such as C.sub.2 to C.sub.6 ether, and at least one highly unsaturated compound, e.g., alkyne and/or alkadienes. Light olefins, defined herein as ethylene,
76
Acetylene
propylene, butylene and mixtures thereof, serve as feeds for the production of numerous important chemicals and polymers. Typically, light olefins are produced by cracking petroleum feeds. Because of the limited supply of competitive petroleum feeds, the opportunities to produce low cost light olefins from petroleum feeds are limited. Efforts to develop light olefin production technologies based on alternative feeds have increased. An important type of alternate feed for the production of light olefins is oxygenate, such as, for example, alcohols, particularly methanol and ethanol, dimethyl ether, methyl ethyl ether, diethyl ether, dimethyl carbonate, and methyl formate. Many of these oxygenates may be produced by fermentation, or from synthesis gas derived from natural gas, petroleum liquids, carbonaceous materials, including coal, recycled plastics, municipal wastes, or any organic material. Because of the wide variety of sources, alcohol, alcohol derivatives, and other oxygenates have promise as an economical, non-petroleum source for light olefin production.

Process for recovery of diene-free feedstocks from olefinic process streams Inventor(s): Foral, Michael J.; (Aurora, IL), Satek, Larry R.; (St. Charles, IL), Ventura, Diadema N.; (Lisle, IL) Correspondence: Carol Wilson; BP America INC.; Mail Code 5 East; 4101 Winfield Road; Warrenville; IL; 60555; US Patent Application Number: 20030105378 Date filed: November 30, 2001 Abstract: Processes using heterogeneous adsorbents are disclosed for purification of olefins such as are typically produced by thermal cracking of suitable hydrocarbon feedstocks. The processes for recovery of diene-free feedstocks includes passing an olefinic process stream containing undesirable levels of propadiene, and optionally hydrocarbon compounds having more than one double bond, small amounts of acetylenic impurities, and/or other organic components, through a particulate bed of heterogeneous adsorbent comprising a metal supported on a high surface area carrier, under conditions suitable for adsorption of dienes. Beneficially, the resulting gaseous mixtures also have reduced levels of other hydrocarbons having more than one double bond, and have reduced levels of acetylenic impurities, such as acetylene and methylacetylene. Processes according to this invention are particularly useful where the olefin being purified is ethylene and/or propylene formed by thermal cracking of hydrocarbon feedstocks from the adsorbent. Excerpt(s): The field of this invention relates to use of heterogeneous adsorbents in purification of relatively impure olefins such as are typically produced by thermal cracking of suitable hydrocarbon feedstocks. More particularly, this invention concerns recovery of diene-free feedstocks by passing an olefinic process stream containing undesirable levels of propadiene, and optionally hydrocarbon compounds of from 4 to about 6 carbon atoms having more than one double bond, small amounts of acetylenic impurities, and/or other organic components, through a particulate bed of heterogeneous adsorbent comprising a metal supported on a high surface area carrier, under conditions suitable for adsorption of dienes. Beneficially, the resulting gaseous mixtures also have reduced levels of other hydrocarbons having more than one double bond, and have reduced levels of acetylenic impurities, such as acetylene and methylacetylene. Processes according to this invention are particularly useful where the olefin being purified is ethylene and/or propylene formed by thermal cracking of hydrocarbon feedstocks. As is well known, olefins, or alkenes, are a homologous series of hydrocarbon compounds characterized by having a double bond of four shared electrons between two carbon atoms. The simplest member of the series, ethylene, is the largest volume organic chemical produced today. Olefins including, importantly, ethylene, propylene and smaller amounts of butadiene, are converted to a multitude of intermediate and end products on a large scale, mainly polymeric materials. Furthermore, sources of relatively impure olefins may also contain undesirable levels of hydrocarbons having more than one double bond, for example dienes such as propadiene, 1,2-butadiene, 1,3-butadiene, 1,2-pentadiene, 1,3-pentadiene, 2,3pentadiene, 2-methyl-1,3-butadiene (isoprene), and cyclopentadiene and/or trienes such as 1,3,5-hexatriene. Commercial production of olefins is, almost exclusively, accomplished by pyrolysis of hydrocarbons in tubular reactor coils installed in externally fired heaters. Thermal cracking feed stocks include streams of ethane, propane or a hydrocarbon liquid ranging in boiling point from light straight-run gasoline through gas oil. Because of the very high temperatures employed, commercial olefin processes invariably coproduce significant amounts of acetylene, methyl

Acetylene
acetylene, and propadiene. Required separation of the more highly unsaturated contaminating compounds from the primary olefin can, considerably, increase the plant cost. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
PROCESS FOR THE SELECTIVE HYDROGENATION OF ALKYNES Inventor(s): Ryu, J. Yong; (League City, TX) Correspondence: Kenneth H. Johnson; P.O. Box 630708; Houston; TX; 77263; US Patent Application Number: 20040092783 Date filed: November 8, 2002 Abstract: An improved selective hydrogenation process for removing acetylenic impurities such as vinyl acetylene, ethyl acetylene, propyl acetylene and acetylene in a steam cracked crude butadiene stream by selective hydrogenation is carried out in two steps. In the first step, the partial selective hydrogenation is carried out in a fixed bed with a copper based catalyst to have the ratio of vinyl acetylene to ethyl acetylene in a range of from 0 to about 1, preferably from about 0.01 to 0.6, in the product stream. In the second step, the selective hydrogenation of the remaining C.sub.4 acetylenic impurities is carried out to the completion in the catalytic distillation mode using a palladium promoted copper catalyst, an improved palladium catalyst or a combination of these two. The product stream from the first step partial hydrogenation is introduced to the catalytic distillation column at a position within the catalytic reaction zone and hydrogen feed gas is introduced below the catalyst bed to maximize the recovery of 1,3butadiene. The feed position to the catalytic distillation column may vary along the catalyst loading zone depending on the feed composition from the first step selective hydrogenation reactor. Optionally, to prolong the catalyst service and cycle time, a solvent is added to the reactor with the hydrocarbon bed stream in the first step or the second step or both steps. Excerpt(s): The present invention relates to the selective removal of more highly unsaturated compounds from mixtures of unsaturated compounds. More particularly the invention is concerned with the selective hydrogenation of acetylenic compounds from mixtures with dienes, such as 1,3-butadiene. The invention provides a novel process for the selective hydrogenation of acetylenes in admixture with other unsaturated compounds. Crude butadiene streams contain undesired multi-unsaturated impurities such as vinyl acetylene, ethyl acetylene, methyl acetylene, etc. These impurities need to be removed to produce high quality 1,3-butadiene product. Although the acetylenes are more reactive in the hydrogenation, 1,3-butadiene is not inert under the selective hydrogenation condition, especially as the conversion of acetylenes approaches to near completion. The concentration of vinyl acetylene in the steam cracked crude butadiene stream is generally much higher than the concentration of ethyl acetylene. The reactivity of vinyl acetylene toward selective hydrogenation is higher than ethyl acetylene. Complete or near complete recovery of 1,3-butadiene and complete removal of both vinyl acetylene and ethyl acetylene is highly desired. However, it is not possible to accomplish this objective in the current commercial processes. In current commercial practice, the selective hydrogenation is carried out in either fixed bed process or catalytic distillation process. Each has its own advantages. The fixed bed unit is easier and cheaper to operate, construct, replace spent catalyst with new catalyst, and regenerate spent catalyst. A catalytic distillation unit generally has higher recovery of 1,3-butadiene and longer catalyst cycle time. But it has higher cost for
Patents 79
the catalyst loading and the deactivated catalyst needs to be removed from the distillation column instead of in-situ regeneration. Also catalytic distillation operation has one less independent process variable than fixed bed operation because the temperature is a function of pressure and composition of the materials in the catalytic distillation column.

Reduced-corrosion inkjet inks and methods for making same Inventor(s): Chatterjee, Amiya K.; (San Diego, CA) Correspondence: Hewlett-packard Company; Intellectual Property Administration; P.O. Box 272400; Fort Collins; CO; 80527-2400; US Patent Application Number: 20030116060 Date filed: December 21, 2001 Abstract: Improved inkjet ink compositions have a sufficient amount of an acetylenic alcohol incorporated therein to reduce the corrosiveness of the ink without adversely affecting the printing characteristics of the ink composition. The inkjet ink compositions of the invention include a carrier, a colorant that is soluble or dispersable in said carrier, and a sufficient quantity of at least one acetylenic alcohol to reduce the corrosiveness of said ink composition to metal placed in contact with said ink composition. The inkjet ink compositions may also include at least one acetylenic alcohol that contains a terminal acetylene and an.alpha.-hydroxy group. A method for reducing corrosiveness of an inkjet ink composition includes adding to said inkjet ink composition a sufficient quantity of at least one acetylenic alcohol to reduce the corrosiveness of said ink composition to metal placed in contact with said ink composition. Excerpt(s): The present invention generally relates to corrosion inhibitors and, more particularly, to inkjet printing formulations which contain corrosion inhibitors and methods of making the same. Ink-jet printing is a non-impact printing process in which droplets of ink are deposited on a print medium. Substantial developments have been made in the field of electronic printing technology, leading to the existence of a wide variety of highly efficient printing systems that are capable of dispensing ink in a rapid and accurate manner. One such system is a thermal inkjet printer that utilizes ink cartridges. Thermal inkjet print cartridges operate by rapidly heating a small volume of ink to cause the ink to vaporize and be ejected through one of a plurality of orifices so as to print a dot of ink on a recording medium, such as a sheet of paper. Typically, the orifices are arranged in one or more linear arrays in a nozzle plate. The properly sequenced ejection of ink from each orifice causes characters or other images to be printed upon the paper as the printhead is moved across the paper. These and other ink jet printing techniques typically impose rigid requirements on the ink compositions. To be suitable for use as a jet ink, the compositions must meet particular requirements. In general, a successful ink set for color ink-jet printing should have good crusting resistance, good stability, proper viscosity, proper surface tension, good color-to-color bleed alleviation, rapid dry time, no negative reaction with the vehicle, consumer-safety, good permanence (e.g., smearfastness, lightfastness, waterfastness), and low strikethrough. Further, the ink must be quick drying and smear resistant and capable of passing through the ink jet nozzle without clogging. The ink should also permit rapid cleanup of the machine components with minimum effort. When placed into a thermal ink-jet system, the ink set should also be kogation-resistant and have stable drop ejection performance (e.g. little or no drop velocity degradation over time).

Selective hydrogenation catalyst Inventor(s): Blankenship, Steven A.; (Radcliff, KY), Perkins, Jennifer A.; (Crestwood, KY), Rokicki, Andrzej; (Prospect, KY) Correspondence: Joan Simunic; 1600 West Hill Street; Louisville; KY; 40210; US Patent Application Number: 20030232719 Date filed: June 12, 2002 Abstract: A catalyst for selective hydrogenation of acetylene including a high surface area support material with a surface area at least about 150 m.sup.2/g and gold wherein the gold comprises from about 0.05 to about 5.0 weight percent of the catalyst and wherein the depth of penetration of the gold into the support material is such that at least about 90 percent of the gold is located within about 250 microns of the surface of the catalyst. A noble metal additive may also be included in the gold catalyst. Excerpt(s): This invention relates to selective hydrogenation catalysts, more particularly to a gold impregnated catalyst with a high surface area carrier, the catalyst being useful for the selective hydrogenation of acetylene in an olefinic feed stream, particularly for ethylene purification. This invention also relates to processes of preparation and use of these catalysts. The manufacture of unsaturated hydrocarbons usually involves cracking various types of hydrocarbons. This often produces a crude product containing hydrocarbon impurities that are more unsaturated than the desired product. An example of this problem occurs with ethylene purification processes, in which acetylene is a common impurity. An example of the process of ethylene purification is described in UK Patent No. 802,100. These unsaturated hydrocarbon impurities are often very difficult to completely remove by fractionation from the desired product. Further, it is often difficult, industrially, to hydrogenate the highly unsaturated hydrocarbon impurities without significant hydrogenation of the desired unsaturated hydrocarbons also occurring. Two general types of gas phase selective hydrogenation processes for removing undesired, unsaturated hydrocarbons are commonly used: "front-end" hydrogenation and "tail-end" hydrogenation. "Front-end" hydrogenation involves passing the crude gas from the initial cracking step, after removal of steam and condensible organic material, over a hydrogenation catalyst. The crude gas generally includes a relatively large volume of hydrogen and a mixture of unsaturated hydrocarbons. Typically, the hydrogen gas concentration is greater than the stoichiometric amount needed for complete hydrogenation of the acetylenes present in the crude gas. To minimize the risk of the excess hydrogen gas hydrogenating ethylene in the feed stream, the hydrogenation catalyst must be very selective. Further, the catalyst risks being damaged in the front-end reactions because hydrogenation of ethylene can lead to thermal excursion, known as "run-away" whereby high temperatures are experienced. Run-away can also result in severe loss of ethylene. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Body Piercing and Branding Are the Latest Fads Source: Skin and Allergy News. 30(12): 27. December 1999. Contact: Available from Skin and Allergy News, Circulation. 12230 Wilkins Avenue, Rockville, MD 20852. (301) 816-8796. Summary: This newsletter article provides health professionals with information on the safety of body piercing and branding. One dermatologist who has studied various forms of body decorations for over 35 years believes that most people who have body art do not experience any problems. Nickel allergy does occur but is not all that common. Bacterial infections from Staphylococcus aureus and Streptococcus seem to cause most problems. Another type of infection common in patients who have body piercings is Pseudomonas. Colonization of this bacteria can liquify ear cartilage and may require treatment with intravenous antibiotics. Candidal infections commonly affect piercings of the navel. Infections are more likely to occur in moist areas such as the genitalia and the nose, mouth piercings rarely become infected. Umbilicus piercings are more prone to infection if exposed to friction. Infections can also occur from trauma-induced tears. Problems are more likely to arise if the piercing is done by an unqualified person. The newest symbols of teenage rebellion are branding and scarification. The latter involves cutting a design into the skin and placing sand or another agent in the wound to promote the formation of a keloid. Branding is performed using a branding iron with initials or some other design on a tip that is heated using an acetylene torch. 6 figures.

Coffee Break: Tutorials for Biologists18 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.19 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.20 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
18 Adapted 19
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 20 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.
97
APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on acetylene can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to acetylene. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to acetylene. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas.
98
Acetylene
You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on acetylene. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits. The National Guideline Clearinghouse™ The National Guideline Clearinghouse™ offers hundreds of evidence-based clinical practice guidelines published in the United States and other countries. You can search this site located at http://www.guideline.gov/ by using the keyword “acetylene” (or synonyms). Healthfinder™ Healthfinder™ is sponsored by the U.S. Department of Health and Human Services and offers links to hundreds of other sites that contain healthcare information. This Web site is located at http://www.healthfinder.gov. Again, keyword searches can be used to find guidelines. The NIH Search Utility The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to acetylene. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. NORD (The National Organization of Rare Disorders, Inc.) NORD provides an invaluable service to the public by publishing short yet comprehensive guidelines on over 1,000 diseases. NORD primarily focuses on rare diseases that might not be covered by the previously listed sources. NORD’s Web address is
Patient Resources
99
http://www.rarediseases.org/. A complete guide on acetylene can be purchased from NORD for a nominal fee. PEDBASE Similar to NORD, PEDBASE covers relatively rare disorders, limited mainly to pediatric conditions. PEDBASE was designed by Dr. Alan Gandy. To access the database, which is more oriented to researchers than patients, you can view the current list of health topics covered at the following Web site: http://www.icondata.com/health/pedbase/pedlynx.htm. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to acetylene. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with acetylene. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about acetylene. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at
100
Acetylene
http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “acetylene” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “acetylene”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “acetylene” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “acetylene” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.21
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.

X-ray therapy: The use of high-energy radiation from x-rays to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy) or from materials called radioisotopes. Radioisotopes produce radiation and can be placed in or near the tumor or in the area near cancer cells. This type of radiation treatment is called internal radiation therapy, implant radiation, interstitial radiation, or brachytherapy. Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that circulates throughout the body. X-ray therapy is also called radiation therapy, radiotherapy, and irradiation. [NIH]
